Struct POGOInfo 

#[repr(C)]
pub struct POGOInfo<'a> {
    pub signature: u32,
    pub data: &'a [u8],
}

Represents the POGO info structure, which provides information about Profile-Guided Optimization (POGO aka PGO) data within a PE file.

PGO is a compiler optimization technique that uses data collected from program execution to optimize code layout and improve runtime performance. This structure contains details such as the relative virtual address (RVA), size, and the associated name of the function or data block for which PGO data is provided.

Fields

signature: u32

The signature of POGO debug directory entry is always first 4-bytes

Either one of:

• IMAGE_DEBUG_POGO_SIGNATURE_LTCG
• IMAGE_DEBUG_POGO_SIGNATURE_PGU

data: &'a [u8]

Raw bytes of POGO debug entry, without first 4-bytes signatures field

Implementations

impl<'a> POGOInfo<'a>

pub fn parse(bytes: &'a [u8], idd: &ImageDebugDirectory) -> Result<Option<Self>>

pub fn parse_with_opts( bytes: &'a [u8], idd: &ImageDebugDirectory, opts: &ParseOptions, ) -> Result<Option<Self>>

pub fn entries(&self) -> POGOEntryIterator<'a>

Returns iterator for POGOInfoEntry

Trait Implementations

impl<'a> Clone for POGOInfo<'a>

fn clone(&self) -> POGOInfo<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Copy for POGOInfo<'a>

impl<'a> Debug for POGOInfo<'a>

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

Formats the value using the given formatter.

impl<'a> Default for POGOInfo<'a>

fn default() -> POGOInfo<'a>

Returns the “default value” for a type.

impl<'a> PartialEq for POGOInfo<'a>

fn eq(&self, other: &POGOInfo<'a>) -> 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.
