Struct ImageCacheSettings 

pub struct ImageCacheSettings {
    pub disk_cache_max_mb: u32,
    pub disk_cache_max_age_hours: u32,
}

图片磁盘缓存配置（uploads/.cache/ 的容量与保留策略）。

Fields

disk_cache_max_mb: u32

最大总容量（MB），超限按修改时间删最旧文件。

disk_cache_max_age_hours: u32

文件最大保留时长（小时），超期优先删除。

Implementations

impl ImageCacheSettings

pub fn clamp_max_mb(n: u32) -> u32

将容量上限钳制到合法范围 [MIN, ∞)。

pub fn clamp_max_age_hours(n: u32) -> u32

将保留时长钳制到合法范围 [MIN, ∞)。

Trait Implementations

impl Clone for ImageCacheSettings

fn clone(&self) -> ImageCacheSettings

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ImageCacheSettings

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

Formats the value using the given formatter.

impl Default for ImageCacheSettings

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ImageCacheSettings

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ImageCacheSettings

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