Struct unwind_context::UnwindContextWithIo

pub struct UnwindContextWithIo<W: Write, T: Debug + DebugAnsiColored, P: PanicDetector> { /* private fields */ }

Available on crate feature std only.

A structure representing a scoped guard with unwind context with core::fmt::Write writer.

If dropped during unwind it will write a message to a given writer containing given function or scope context.

When this structure is dropped (falls out of scope) and the current thread is not unwinding, the unwind context will be forgotten.

Examples

use unwind_context::{unwind_context, UnwindContextWithIo};

fn func(foo: u32, bar: &str, secret: &str) {
    let _ctx: UnwindContextWithIo<_, _, _> = unwind_context!(fn(foo, bar, ...));
    // ...
}

Implementations

impl<W: Write, T: Debug + DebugAnsiColored, P: PanicDetector> UnwindContextWithIo<W, T, P>

pub fn new( data: T, writer: W, panic_detector: P, color_scheme: Option<&'static AnsiColorScheme> ) -> Self

Create a new UnwindContextWithFmt with the provided core::fmt::Write writer, context scope data, and color scheme.

This function is not intended to be used directly. Consider using macros like unwind_context or unwind_context_with_io instead.

pub fn print(&mut self)

Print context to a writer specified in the UnwindContextWithIo constructor.

This method is called when a panic detected.

Trait Implementations

impl<W: Clone + Write, T: Clone + Debug + DebugAnsiColored, P: Clone + PanicDetector> Clone for UnwindContextWithIo<W, T, P>

fn clone(&self) -> UnwindContextWithIo<W, T, P>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<W: Debug + Write, T: Debug + Debug + DebugAnsiColored, P: Debug + PanicDetector> Debug for UnwindContextWithIo<W, T, P>

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

Formats the value using the given formatter.

impl<W: Write, T: Debug + DebugAnsiColored, P: PanicDetector> Drop for UnwindContextWithIo<W, T, P>

fn drop(&mut self)

Executes the destructor for this type.

impl<W: Hash + Write, T: Hash + Debug + DebugAnsiColored, P: Hash + PanicDetector> Hash for UnwindContextWithIo<W, T, P>

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

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<W: Ord + Write, T: Ord + Debug + DebugAnsiColored, P: Ord + PanicDetector> Ord for UnwindContextWithIo<W, T, P>

fn cmp(&self, other: &UnwindContextWithIo<W, T, P>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl<W: PartialEq + Write, T: PartialEq + Debug + DebugAnsiColored, P: PartialEq + PanicDetector> PartialEq for UnwindContextWithIo<W, T, P>

fn eq(&self, other: &UnwindContextWithIo<W, T, P>) -> 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.

impl<W: PartialOrd + Write, T: PartialOrd + Debug + DebugAnsiColored, P: PartialOrd + PanicDetector> PartialOrd for UnwindContextWithIo<W, T, P>

fn partial_cmp(&self, other: &UnwindContextWithIo<W, T, P>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
