Struct SubFormat 

pub struct SubFormat;

Subtitle format implementation for MicroDVD/SubViewer SUB.

The SubFormat struct implements parsing, serialization, and detection for SUB files using frame-based timing. See the parser module documentation for the malformed-input disposition matrix observed by SubFormat::parse.

Trait Implementations

impl SubtitleFormat for SubFormat

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

Parse SUB content.

Malformed-input dispositions

• Empty input → returns crate::error::SubXError::SubtitleFormat.
• A single cue whose body exceeds the per-cue cap (1 MiB) → returns crate::error::SubXError::SubtitleFormat.
• Non-numeric frame range (line that does not match {\d+}{\d+}) → skipped with a debug! log; parsing continues.
• Frame number that decodes to > 24 h → skipped with a debug! log; parsing continues.

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.
