    pub allow_network: bool,
    pub max_concurrent: u32,
    pub max_cpu_cores: f64,
    pub max_memory_mb: u32,

    pub languages: Option<String>,
}

代码运行器配置（资源限制与并发）。

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

allow_network: bool

是否允许容器联网。

max_concurrent: u32

最大并发任务数。

max_cpu_cores: f64

每任务最大 CPU 核数。

max_memory_mb: u32

每任务最大内存（MB）。

max_timeout_secs: u32

每任务最大执行超时（秒）。

max_output_bytes: u64

每任务最大输出字节数。

max_source_bytes: u64

每任务最大源码字节数。

queue_timeout_secs: u32

排队等待超时（秒）。

task_ttl_secs: u32

历史 task 保留时长（秒）。

languages: Option<String>

语言白名单（逗号分隔，如 “python,node,rust”）；None 表示不限制（全开）。

Implementations

impl RunnerSettings

pub fn clamp_max_concurrent(n: u32) -> u32

将最大并发钳制到合法范围 [1, 64]。

pub fn clamp_max_cpu_cores(n: f64) -> f64

将 CPU 核数钳制到合法范围 [0.1, 64.0]；NaN 回退默认值。

pub fn clamp_max_memory_mb(n: u32) -> u32

将内存钳制到合法范围 [16, 65536]。

pub fn clamp_max_timeout_secs(n: u32) -> u32

将超时钳制到合法范围 [1, ∞)。

pub fn clamp_max_output_bytes(n: u64) -> u64

将输出上限钳制到合法范围 [1, ∞)。

pub fn clamp_max_source_bytes(n: u64) -> u64

将源码上限钳制到合法范围 [1, ∞)。

pub fn clamp_queue_timeout_secs(n: u32) -> u32

将排队超时钳制到合法范围 [1, ∞)。

pub fn clamp_task_ttl_secs(n: u32) -> u32

将 task 保留时长钳制到合法范围 [1, ∞)。

pub fn normalize_languages(s: &str) -> Option<String>

规范化语言白名单字符串：拆分、trim、转小写、去空；结果为空则返回 None。

Trait Implementations

impl Clone for RunnerSettings

fn clone(&self) -> RunnerSettings

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RunnerSettings

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

Formats the value using the given formatter.

impl Default for RunnerSettings

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RunnerSettings

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RunnerSettings

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
