Struct SrtFormat 

pub struct SrtFormat;

SubRip (.srt) format parsing and serialization.

Trait Implementations

impl SubtitleFormat for SrtFormat

fn parse(&self, content: &str) -> Result<Subtitle>

Parse SRT content into a Subtitle.

Malformed-input dispositions

Per the subtitle-parser-hardening spec matrix, this parser handles malformed inputs as follows:

• Empty input → returns crate::error::SubXError::SubtitleFormat.
• UTF-8 BOM prefix → consumed as a defensive layer at the start of parse (additive to the encoding-layer formats::encoding::converter::skip_bom); BOM-only content reduces to empty input and is rejected.
• Per-cue body exceeding MAX_CUE_BYTES (1 MiB) → returns crate::error::SubXError::SubtitleFormat. The cap is enforced on raw pre-normalization bytes, so \r\n padding cannot bypass the limit by shrinking under line-ending normalization.
• CRLF (\r\n), bare-CR (\r), or mixed line endings → input is normalized to LF before block splitting; CRLF and mixed inputs parse to the same entry count and text content as their LF counterpart.
• Block with non-numeric sequence index → skip-and-continue with debug! log.
• Block with negative timestamp on the timing line → skip-and-continue with debug! log.
• Block whose timing line does not match the SRT regex → silently skipped (existing tolerated behavior).
• Out-of-order cues by start time → preserved verbatim in entries; no implicit sort.

fn serialize(&self, subtitle: &Subtitle) -> Result<String>

Serialize a Subtitle structure into format-specific text representation.

fn detect(&self, content: &str) -> bool

Detect whether the provided content matches this subtitle format.

fn format_name(&self) -> &'static str

Returns the human-readable name of this subtitle format.

fn file_extensions(&self) -> &'static [&'static str]

Returns the list of supported file extensions for this format.

fn supports_styling(&self) -> bool

Check if this format supports advanced styling features.

fn uses_frame_timing(&self) -> bool

Check if this format uses frame-based timing.
