Struct wasmer_compiler::engine::trap::frame_info::GlobalFrameInfo

pub struct GlobalFrameInfo {
    ranges: BTreeMap<usize, ModuleInfoFrameInfo>,
}

Fields

ranges: BTreeMap<usize, ModuleInfoFrameInfo>

An internal map that keeps track of backtrace frame information for each module.

This map is morally a map of ranges to a map of information for that module. Each module is expected to reside in a disjoint section of contiguous memory. No modules can overlap.

The key of this map is the highest address in the module and the value is the module’s information, which also contains the start address.

Implementations

impl GlobalFrameInfo

pub fn lookup_frame_info(&self, pc: usize) -> Option<FrameInfo>

Fetches frame information about a program counter in a backtrace.

Returns an object if this pc is known to some previously registered module, or returns None if no information can be found.

pub fn lookup_trap_info(&self, pc: usize) -> Option<TrapInformation>

Fetches trap information about a program counter in a backtrace.

fn module_info(&self, pc: usize) -> Option<&ModuleInfoFrameInfo>

Gets a module given a pc

Trait Implementations

impl Default for GlobalFrameInfo

fn default() -> GlobalFrameInfo

Returns the “default value” for a type.
