Struct Replacer

pub struct Replacer<'a> { /* private fields */ }

Replacer replaces a list of slices with replacements. It is safe for concurrent use by multiple goroutines.

zh-cn

Replacer类型进行一系列字节切片的替换。

Implementations

impl<'a> Replacer<'a>

pub fn new(pairs: Vec<(&'a [byte], &'a [byte])>) -> Replacer<'a>

new returns a new Replacer from a list of old, new bytes pairs. Replacements are performed in the order they appear in the target string, without overlapping matches. The old string comparisons are done in argument order.

zh-cn

使用提供的多组old、new字节切片对创建并返回一个*Replacer。替换是依次进行的，匹配时不会重叠。

Example

use gostd_bytes as bytes;

   let p = vec![("<".as_bytes(), "&lt;".as_bytes()), (">".as_bytes(), "&gt;".as_bytes())];
   let r = bytes::Replacer::new(p);
   let s = r.Replace("This is <b>HTML</b>!".as_bytes());
   println!("{}", String::from_utf8(s).unwrap());

Output

This is <b>HTML</b>!

pub fn Replace(self, s: &[byte]) -> Vec<byte>

Replace returns a copy of s with all replacements performed.

zh-cn

Replace返回s的所有替换进行完后的拷贝.

pub fn WriteString(&self, w: Box<dyn Writer>, s: &str) -> Result<int, Error>

WriteString writes s to w with all replacements performed.

zh-cn

WriteString向w中写入s的所有替换进行完后的拷贝
