Struct wasmtime::FrameSymbol

source ·
pub struct FrameSymbol { /* private fields */ }
Expand description

Debug information for a symbol that is attached to a FrameInfo.

When DWARF debug information is present in a wasm file then this structure can be found on a FrameInfo and can be used to learn about filenames, line numbers, etc, which are the origin of a function in a stack trace.

Implementations§

source§

impl FrameSymbol

source

pub fn name(&self) -> Option<&str>

Returns the function name associated with this symbol.

Note that this may not be present with malformed debug information, or the debug information may not include it. Also note that the symbol is frequently mangled, so you might need to run some form of demangling over it.

source

pub fn file(&self) -> Option<&str>

Returns the source code filename this symbol was defined in.

Note that this may not be present with malformed debug information, or the debug information may not include it.

source

pub fn line(&self) -> Option<u32>

Returns the 1-indexed source code line number this symbol was defined on.

Note that this may not be present with malformed debug information, or the debug information may not include it.

source

pub fn column(&self) -> Option<u32>

Returns the 1-indexed source code column number this symbol was defined on.

Note that this may not be present with malformed debug information, or the debug information may not include it.
