Struct TypeInfoEntry 

pub struct TypeInfoEntry<'a> { /* private fields */ }

Zero-copy view of an MSFT_TypeInfoBase structure (0x64 bytes).

Each TypeInfo describes one type in the library: an enum, struct, module, COM interface, dispatch interface, coclass, alias, or union.

Constructed by TypeLib::typeinfo; the backing slice is guaranteed to be at least SIZE bytes.

Implementations

impl<'a> TypeInfoEntry<'a>

pub const SIZE: usize = 0x64

Size of the fixed MSFT_TypeInfoBase structure in bytes.

pub fn as_bytes(&self) -> &'a [u8]

Returns the raw backing bytes.

pub fn typekind(&self) -> TypeKind

Type kind (low 4 bits of the typekind field).

pub fn typekind_raw(&self) -> u32

Raw typekind field (includes alignment in bits 11-15).

pub fn memoffset(&self) -> i32

Absolute file offset to the func/var data block.

Returns a negative value when no data block exists.

pub fn res2(&self) -> i32

First reference offset in pRefTab (for coclasses), or -1.

pub fn celement(&self) -> u32

Raw cElement field.

Low 16 bits = function count, high 16 bits = variable count.

pub fn func_count(&self) -> u16

Number of functions (low 16 bits of cElement).

pub fn var_count(&self) -> u16

Number of variables (high 16 bits of cElement).

pub fn guid_offset(&self) -> i32

Offset into the GUID table, or -1 if this type has no GUID.

pub fn flags(&self) -> u32

TYPEFLAG_* flags.

pub fn name_offset(&self) -> i32

Offset into the name table for this type’s name.

pub fn version(&self) -> u32

Element version (set with SetVersion).

pub fn docstring_offset(&self) -> i32

Offset into the string table for the doc string, or -1.

pub fn cimpltypes(&self) -> i16

Number of implemented interfaces (for coclasses).

pub fn cb_size_vft(&self) -> i16

Virtual function table size in bytes.

pub fn size(&self) -> i32

Instance size in bytes.

pub fn datatype1(&self) -> i32

For ALIAS types: the aliased type descriptor. Otherwise -1.

pub fn datatype2(&self) -> i32

For ALIAS types: secondary aliased type descriptor. Otherwise -1.

pub fn helpstringcontext(&self) -> i32

Help string context at offset 0x40.

pub fn helpcontext(&self) -> i32

Help context at offset 0x44.

pub fn cust_data_offset(&self) -> i32

Offset into the CDGuids directory for this type’s custom data, or -1.

pub fn res3(&self) -> i32

Reserved field at offset 0x0C (-1 if no element, else (N-1)*0x38).

pub fn res18(&self) -> i32

Reserved field at offset 0x5C (always 0).

pub fn res19(&self) -> i32

Reserved field at offset 0x60 (always -1).

Trait Implementations
