Struct wasmtime_cranelift_shared::FunctionAddressMap

pub struct FunctionAddressMap {
    pub instructions: Box<[InstructionAddressMap]>,
    pub start_srcloc: FilePos,
    pub end_srcloc: FilePos,
    pub body_offset: usize,
    pub body_len: u32,
}

Metadata to translate from binary offsets back to the original location found in the wasm input.

Fields

instructions: Box<[InstructionAddressMap]>

An array of data for the instructions in this function, indicating where each instruction maps back to in the original function.

This array is sorted least-to-greatest by the code_offset field. Additionally the span of each InstructionAddressMap is implicitly the gap between it and the next item in the array.

start_srcloc: FilePos

Function’s initial offset in the source file, specified in bytes from the front of the file.

end_srcloc: FilePos

Function’s end offset in the source file, specified in bytes from the front of the file.

body_offset: usize

Generated function body offset if applicable, otherwise 0.

body_len: u32

Generated function body length.

Trait Implementations

impl Clone for FunctionAddressMap

fn clone(&self) -> FunctionAddressMap

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FunctionAddressMap

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

Formats the value using the given formatter.

impl Default for FunctionAddressMap

fn default() -> FunctionAddressMap

Returns the “default value” for a type.

impl PartialEq for FunctionAddressMap

fn eq(&self, other: &FunctionAddressMap) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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