Struct ThreadUnsafeWriteDropStrategy 

pub struct ThreadUnsafeWriteDropStrategy<W: Write> {
    pub writer: RefCell<W>,
    pub new_line: bool,
    pub prelude: Option<Vec<u8>>,
}

A drop strategy which writes the message of an error to a writer. While more efficient than it’s thread safe counterpart, it’s less flexible.

Fields

writer: RefCell<W>

The writer to write to.

new_line: bool

Whether or not to append a newline to the end of the message.

prelude: Option<Vec<u8>>

The message to add at the beginning of the message.

Implementations

impl<W: Write> ThreadUnsafeWriteDropStrategy<W>

pub fn new(writer: W) -> Self

Creates a new ThreadUnsafeWriteDropStrategy with the given writer.

pub fn new_line(&mut self, new_line: bool) -> &mut Self

Sets whether or not to append a newline to the end of the message.

pub fn prelude(&mut self, prelude: impl Into<Vec<u8>>) -> &mut Self

Sets the message to add at the beginning of the message.

impl ThreadUnsafeWriteDropStrategy<Stderr>

pub fn stderr() -> Self

Write to standard error.

impl ThreadUnsafeWriteDropStrategy<Stdout>

pub fn stdout() -> Self

Write to standard output.

Trait Implementations

impl<W: Clone + Write> Clone for ThreadUnsafeWriteDropStrategy<W>

fn clone(&self) -> ThreadUnsafeWriteDropStrategy<W>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<W: Debug + Write> Debug for ThreadUnsafeWriteDropStrategy<W>

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

Formats the value using the given formatter.

impl<W: Write> FallibleTryDropStrategy for ThreadUnsafeWriteDropStrategy<W>

type Error = Error

The type of the error that may occur when handling a drop error.

fn try_handle_error(&self, error: Error) -> Result<(), Self::Error>

Try and handle a drop error.

impl<W: Ord + Write> Ord for ThreadUnsafeWriteDropStrategy<W>

fn cmp(&self, other: &ThreadUnsafeWriteDropStrategy<W>) -> 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,

Restrict a value to a certain interval.

impl<W: PartialEq + Write> PartialEq for ThreadUnsafeWriteDropStrategy<W>

fn eq(&self, other: &ThreadUnsafeWriteDropStrategy<W>) -> 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<W: PartialOrd + Write> PartialOrd for ThreadUnsafeWriteDropStrategy<W>

fn partial_cmp( &self, other: &ThreadUnsafeWriteDropStrategy<W>, ) -> Option<Ordering>

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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