Struct Replace 

pub struct Replace<A, B, C> {
    pub source: A,
    pub needle: B,
    pub replacement: C,
}

A Writeable adapter that replaces occurrences of a needle with a replacement.

This adapter performs the replacement in a streaming fashion during write_to, requiring zero allocations.

Examples

use writeable::adapters::Replace;
use writeable::assert_writeable_eq;
use writeable::concat_writeable;

let source = concat_writeable!("I 💖 🦀", " and 🦀 loves me!");
let replace = Replace {
    source,
    needle: "🦀",
    replacement: "Rust",
};

assert_writeable_eq!(replace, "I 💖 Rust and Rust loves me!");

Fields

source: A

The source writeable.

needle: B

The needle to search for.

replacement: C

The replacement writeable.

Trait Implementations

impl<A: Debug, B: Debug, C: Debug> Debug for Replace<A, B, C>

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

Formats the value using the given formatter.

impl<'a, A: Writeable, C: Writeable> Display for Replace<A, &'a str, C>

This trait is implemented for compatibility with fmt!. To create a string, [Writeable::write_to_string] is usually more efficient.

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

Formats the value using the given formatter.

impl<A, C> Writeable for Replace<A, &str, C>

where A: Writeable, C: Writeable,

fn write_to<W: Write + ?Sized>(&self, sink: &mut W) -> Result

Writes a string to the given sink. Errors from the sink are bubbled up. The default implementation delegates to write_to_parts, and discards any Part annotations.

fn writeable_length_hint(&self) -> LengthHint

Returns a hint for the number of UTF-8 bytes that will be written to the sink.

fn write_to_parts<S: PartsWrite + ?Sized>(&self, sink: &mut S) -> Result

Write bytes and Part annotations to the given sink. Errors from the sink are bubbled up. The default implementation delegates to write_to, and doesn’t produce any Part annotations.

fn writeable_borrow(&self) -> Option<&str>

Returns a &str that matches the output of write_to, if possible.
