Crate skrt 

A library for parsing and manipulating SubRip Text (SRT) subtitle files.

SRT is a simple, widely-supported subtitle format used by media players, video editors, and streaming platforms. Each subtitle entry consists of:

• A sequential index number
• A timestamp range (start –> end)
• One or more lines of text

Example

use skrt::{Srt, Timestamp};

// Parse an existing SRT file
let data = r#"1
00:00:01,000 --> 00:00:04,000
Hello, world!

2
00:00:05,000 --> 00:00:08,000
This is a subtitle.

"#;

let srt = Srt::try_parse(data).unwrap();
assert_eq!(2, srt.subtitles().len());

// Or build one programmatically
let mut srt = Srt::new();
srt.add_subtitle(
    Timestamp::from_millis(1000).unwrap(),
    Timestamp::from_millis(4000).unwrap(),
    "Hello, world!".into(),
);

let output = srt.serialize();

Format Details

This crate handles common SRT variations:

• Both LF and CRLF line endings
• Optional UTF-8 BOM at the start of the file
• Trailing whitespace after timestamps
• Files that don’t end with a blank line

Timestamps follow the format HH:MM:SS,mmm where:

• HH = hours (00-99)
• MM = minutes (00-59)
• SS = seconds (00-59)
• mmm = milliseconds (000-999)
