Struct custom_print::WriteBytesFn

pub struct WriteBytesFn<F, R>(_)
where
         F: FnMut(&[u8]) -> R;

A wrapper for write functions for<R> FnMut(&[u8]) -> R.

It implements WriteBytes and WriteStr traits and can be used in conjunction with IntoWriteFn and IntoTryWriteFn traits to simplify type inference.

Implementations

impl<F, R> WriteBytesFn<F, R>where F: FnMut(&[u8]) -> R,

pub fn new(closure: F) -> Self

Creates a new WriteBytesFn containing the given closure or function.

Trait Implementations

impl<F, R: Clone> Clone for WriteBytesFn<F, R>where F: FnMut(&[u8]) -> R + Clone,

fn clone(&self) -> WriteBytesFn<F, R>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<F, R: Debug> Debug for WriteBytesFn<F, R>where F: FnMut(&[u8]) -> R + Debug,

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

Formats the value using the given formatter.

impl<F, R: PartialEq> PartialEq<WriteBytesFn<F, R>> for WriteBytesFn<F, R>where F: FnMut(&[u8]) -> R + PartialEq,

fn eq(&self, other: &WriteBytesFn<F, R>) -> 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<F, R> WriteBytes for WriteBytesFn<F, R>where F: FnMut(&[u8]) -> R,

type Output = R

The resulting type after writing.

fn write_bytes(&mut self, buf: &[u8]) -> Self::Output

Performs byte writing.

impl<F, R: Copy> Copy for WriteBytesFn<F, R>where F: FnMut(&[u8]) -> R + Copy,

impl<F, R: Eq> Eq for WriteBytesFn<F, R>where F: FnMut(&[u8]) -> R + Eq,

impl<F, R> StructuralEq for WriteBytesFn<F, R>where F: FnMut(&[u8]) -> R,

impl<F, R> StructuralPartialEq for WriteBytesFn<F, R>where F: FnMut(&[u8]) -> R,

impl<F, R> WriteStrAsBytes for WriteBytesFn<F, R>where F: FnMut(&[u8]) -> R,
