Struct WebpSettings 

pub struct WebpSettings {
    pub quality: f32,
    pub method: u32,
}

WebP 有损编码配置（质量与方法）。

需重启生效层：值在进程启动时烘焙进 LazyLock，改 DB 值后需重启才生效。

Fields

quality: f32

质量系数，范围 0.0–100.0。

method: u32

编码方法，范围 0–6，数值越大压缩率越高但越慢。

Implementations

impl WebpSettings

pub fn clamp_quality(q: f32) -> f32

将质量钳制到合法范围 [0.0, 100.0]。

pub fn clamp_method(m: u32) -> u32

将编码方法钳制到合法范围 [0, 6]。

Trait Implementations

impl Clone for WebpSettings

fn clone(&self) -> WebpSettings

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WebpSettings

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

Formats the value using the given formatter.

impl Default for WebpSettings

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for WebpSettings

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for WebpSettings

fn eq(&self, other: &WebpSettings) -> 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 Serialize for WebpSettings

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
