Enum SubtitleCodec 

pub enum SubtitleCodec {
    Srt,
    Ass,
    Dvb,
    Hdmv,
    Webvtt,
    Other(String),
}

Subtitle codec identifier.

This enum represents common subtitle codecs used in media files. It covers text-based and bitmap-based formats while remaining extensible via the Other variant.

Note: No Copy or Default derive because Other(String) is not Copy.

Variants

Srt

SubRip / SRT — text-based timed subtitles

Ass

ASS/SSA (Advanced SubStation Alpha) — styled text subtitles

Dvb

DVB bitmap subtitles (digital broadcast)

Hdmv

HDMV/PGS — Blu-ray bitmap subtitles

Webvtt

WebVTT — web-standard text subtitles

Other(String)

Unrecognized codec; raw codec name stored for transparency

Implementations

impl SubtitleCodec

pub fn name(&self) -> &str

Returns the codec name as a short string.

Examples

use ff_format::codec::SubtitleCodec;

assert_eq!(SubtitleCodec::Srt.name(), "srt");
assert_eq!(SubtitleCodec::Ass.name(), "ass");

pub fn display_name(&self) -> &str

Returns the human-readable display name for the codec.

Examples

use ff_format::codec::SubtitleCodec;

assert_eq!(SubtitleCodec::Srt.display_name(), "SubRip (SRT)");
assert_eq!(SubtitleCodec::Hdmv.display_name(), "HDMV/PGS");

pub fn is_text_based(&self) -> bool

Returns true if this is a text-based subtitle codec.

Examples

use ff_format::codec::SubtitleCodec;

assert!(SubtitleCodec::Srt.is_text_based());
assert!(SubtitleCodec::Ass.is_text_based());
assert!(!SubtitleCodec::Dvb.is_text_based());

pub fn is_bitmap_based(&self) -> bool

Returns true if this is a bitmap-based subtitle codec.

Examples

use ff_format::codec::SubtitleCodec;

assert!(SubtitleCodec::Dvb.is_bitmap_based());
assert!(SubtitleCodec::Hdmv.is_bitmap_based());
assert!(!SubtitleCodec::Srt.is_bitmap_based());

pub fn is_unknown(&self) -> bool

Returns true if the codec is unrecognized.

Examples

use ff_format::codec::SubtitleCodec;

assert!(SubtitleCodec::Other("dvd_subtitle".to_string()).is_unknown());
assert!(!SubtitleCodec::Srt.is_unknown());

Trait Implementations

impl Clone for SubtitleCodec

fn clone(&self) -> SubtitleCodec

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SubtitleCodec

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

Formats the value using the given formatter.

impl Display for SubtitleCodec

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

Formats the value using the given formatter.

impl Hash for SubtitleCodec

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SubtitleCodec

fn eq(&self, other: &SubtitleCodec) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
