Struct zng::app::crash_handler::BacktraceFrame

pub struct BacktraceFrame {
    pub n: usize,
    pub name: Txt,
    pub file: Txt,
    pub line: u32,
    pub is_after_panic: bool,
}

Represents a frame parsed from a stack backtrace.

Fields

n: usize

Position on the backtrace.

name: Txt

Function name.

file: Txt

Source code file.

line: u32

Source code line.

is_after_panic: bool

If this frame is inside the Rust panic code.

Implementations

impl BacktraceFrame

pub fn parse(backtrace: &str) -> impl Iterator<Item = BacktraceFrame>

Iterate over frames parsed from the backtrace.

pub fn code_snippet(&self) -> Txt

Reads the code line + four surrounding lines if the code file can be found.

Trait Implementations

impl Clone for BacktraceFrame

fn clone(&self) -> BacktraceFrame

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BacktraceFrame

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BacktraceFrame

fn deserialize<__D>( __deserializer: __D, ) -> Result<BacktraceFrame, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for BacktraceFrame

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

Formats the value using the given formatter.

impl Hash for BacktraceFrame

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for BacktraceFrame

fn eq(&self, other: &BacktraceFrame) -> 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.

impl Serialize for BacktraceFrame

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
