Enum Preset 

#[non_exhaustive]
pub enum Preset {
    Ultrafast,
    Faster,
    Fast,
    Medium,
    Slow,
    Slower,
    Veryslow,
}

Encoding preset (speed vs quality tradeoff).

Presets control the speed/quality balance during encoding:

• Faster presets = faster encoding, lower quality, larger file size
• Slower presets = slower encoding, higher quality, smaller file size

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Ultrafast

Ultra fast (low quality)

Faster

Faster

Fast

Fast

Medium

Medium (balanced)

Slow

Slow (high quality)

Slower

Slower

Veryslow

Very slow (highest quality)

Implementations

impl Preset

pub const fn as_str(self) -> &'static str

Convert to FFmpeg preset string.

Trait Implementations

impl Clone for Preset

fn clone(&self) -> Preset

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Preset

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

Formats the value using the given formatter.

impl Default for Preset

fn default() -> Preset

Returns the “default value” for a type.

impl PartialEq for Preset

fn eq(&self, other: &Preset) -> 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.

impl Copy for Preset

impl Eq for Preset

impl StructuralPartialEq for Preset
