Struct SBAddress 

pub struct SBAddress {
    pub raw: SBAddressRef,
}

A section + offset based address class.

The SBAddress class allows addresses to be relative to a section that can move during runtime due to images (executables, shared libraries, bundles, frameworks) being loaded at different addresses than the addresses found in the object file that represents them on disk. There are currently two types of addresses for a section:

• file addresses
• load addresses

File addresses represents the virtual addresses that are in the ‘on disk’ object files. These virtual addresses are converted to be relative to unique sections scoped to the object file so that when/if the addresses slide when the images are loaded/unloaded in memory, we can easily track these changes without having to update every object (compile unit ranges, line tables, function address ranges, lexical block and inlined subroutine address ranges, global and static variables) each time an image is loaded or unloaded.

Load addresses represents the virtual addresses where each section ends up getting loaded at runtime. Before executing a program, it is common for all of the load addresses to be unresolved. When a DynamicLoader plug-in receives notification that shared libraries have been loaded/unloaded, the load addresses of the main executable and any images (shared libraries) will be resolved/unresolved. When this happens, breakpoints that are in one of these sections can be set/cleared.

Fields

raw: SBAddressRef

The underlying raw SBAddressRef.

Implementations

impl SBAddress

pub fn is_valid(&self) -> bool

Check whether or not this is a valid SBAddress value.

pub fn from_section_offset( section: &SBSection, offset: lldb_addr_t, ) -> SBAddress

Construct a new SBAddress from the given section and offset.

pub fn from_load_address(load_addr: lldb_addr_t, target: &SBTarget) -> SBAddress

Create a new SBAddress from the given load address within the target.

pub fn file_address(&self) -> u64

The address that represents the address as it is found in the object file that defines it.

pub fn load_address(&self, target: &SBTarget) -> u64

The address as it has been loaded into memory by a target.

pub fn symbol_context(&self, resolve_scope: u32) -> SBSymbolContext

Get the SBSymbolContext for a given address.

An address might refer to code or data from an existing module, or it might refer to something on the stack or heap. This will only return valid values if the address has been resolved to a code or data address using SBAddress::from_load_address or SBTarget::resolve_load_address.

• resolve_scope: Flags that specify what type of symbol context is needed by the caller. These flags have constants starting with SYMBOL_CONTEXT_ITEM_.

pub fn module(&self) -> Option<SBModule>

Get the SBModule for a given address.

An address might refer to code or data from an existing module, or it might refer to something on the stack or heap. This will only return valid values if the address has been resolved to a code or data address using SBAddress::from_load_address or SBTarget::resolve_load_address.

This grabs an individual object for a given address and is less efficient if you want more than one symbol related objects. Use one of the following when you want multiple debug symbol related objects for an address:

• SBAddress::symbol_context
• SBTarget::resolve_symbol_context_for_address

One or more bits from the SymbolContextItem enumerations can be logically OR’ed together to more efficiently retrieve multiple symbol objects.

pub fn compile_unit(&self) -> Option<SBCompileUnit>

Get the SBCompileUnit for a given address.

An address might refer to code or data from an existing module, or it might refer to something on the stack or heap. This will only return valid values if the address has been resolved to a code or data address using SBAddress::from_load_address or SBTarget::resolve_load_address.

This grabs an individual object for a given address and is less efficient if you want more than one symbol related objects. Use one of the following when you want multiple debug symbol related objects for an address:

• SBAddress::symbol_context
• SBTarget::resolve_symbol_context_for_address

One or more bits from the SymbolContextItem enumerations can be logically OR’ed together to more efficiently retrieve multiple symbol objects.

pub fn function(&self) -> Option<SBFunction>

Get the SBFunction for a given address.

An address might refer to code or data from an existing module, or it might refer to something on the stack or heap. This will only return valid values if the address has been resolved to a code or data address using SBAddress::from_load_address or SBTarget::resolve_load_address.

This grabs an individual object for a given address and is less efficient if you want more than one symbol related objects. Use one of the following when you want multiple debug symbol related objects for an address:

• SBAddress::symbol_context
• SBTarget::resolve_symbol_context_for_address

One or more bits from the SymbolContextItem enumerations can be logically OR’ed together to more efficiently retrieve multiple symbol objects.

pub fn block(&self) -> Option<SBBlock>

Get the SBBlock for a given address.

An address might refer to code or data from an existing module, or it might refer to something on the stack or heap. This will only return valid values if the address has been resolved to a code or data address using SBAddress::from_load_address or SBTarget::resolve_load_address.

This grabs an individual object for a given address and is less efficient if you want more than one symbol related objects. Use one of the following when you want multiple debug symbol related objects for an address:

• SBAddress::symbol_context
• SBTarget::resolve_symbol_context_for_address

One or more bits from the SymbolContextItem enumerations can be logically OR’ed together to more efficiently retrieve multiple symbol objects.

pub fn symbol(&self) -> Option<SBSymbol>

Get the SBSymbol for a given address.

An address might refer to code or data from an existing module, or it might refer to something on the stack or heap. This will only return valid values if the address has been resolved to a code or data address using SBAddress::from_load_address or SBTarget::resolve_load_address.

This grabs an individual object for a given address and is less efficient if you want more than one symbol related objects. Use one of the following when you want multiple debug symbol related objects for an address:

• SBAddress::symbol_context
• SBTarget::resolve_symbol_context_for_address

One or more bits from the SymbolContextItem enumerations can be logically OR’ed together to more efficiently retrieve multiple symbol objects.

pub fn line_entry(&self) -> Option<SBLineEntry>

Get the SBLineEntry for a given address.

An address might refer to code or data from an existing module, or it might refer to something on the stack or heap. This will only return valid values if the address has been resolved to a code or data address using SBAddress::from_load_address or SBTarget::resolve_load_address.

This grabs an individual object for a given address and is less efficient if you want more than one symbol related objects. Use one of the following when you want multiple debug symbol related objects for an address:

• SBAddress::symbol_context
• SBTarget::resolve_symbol_context_for_address

One or more bits from the SymbolContextItem enumerations can be logically OR’ed together to more efficiently retrieve multiple symbol objects.

pub fn get_offset(&self) -> lldb_addr_t

Returns offset of the address in the section

See also:

• get_section for getting the section corresponding to this address

pub fn get_section(&self) -> Option<SBSection>

Returns the corresponding section of this address.
