Struct FunctionRegistry

pub struct FunctionRegistry<T> { /* private fields */ }

Holds the function symbols of an Executable

Implementations

impl<T> FunctionRegistry<T>

where T: Copy + PartialEq,

pub fn register_function( &mut self, key: u32, name: impl Into<Vec<u8>>, value: T, ) -> Result<(), ElfError>

Register a symbol with an explicit key

pub fn register_function_hashed( &mut self, name: impl Into<Vec<u8>>, value: T, ) -> Result<u32, ElfError>

Register a symbol with an implicit key

pub fn unregister_function(&mut self, key: u32)

Unregister a symbol again

pub fn keys(&self) -> impl Iterator<Item = u32>

Iterate over all keys

pub fn iter(&self) -> impl Iterator<Item = (u32, (&[u8], T))>

Iterate over all entries

pub fn lookup_by_key(&self, key: u32) -> Option<(&[u8], T)>

Get a function by its key

pub fn lookup_by_name(&self, name: &[u8]) -> Option<(&[u8], T)>

Get a function by its name

pub fn mem_size(&self) -> usize

Calculate memory size

Trait Implementations

impl<T> Debug for FunctionRegistry<T>

where T: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<T> Default for FunctionRegistry<T>

fn default() -> FunctionRegistry<T>

Returns the “default value” for a type.

impl<T> PartialEq for FunctionRegistry<T>

where T: PartialEq,

fn eq(&self, other: &FunctionRegistry<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
