Enum Level 

#[repr(i32)]
pub enum Level {
    Unset = 0,
    Debug = 1,
    Info = 2,
    Warn = 3,
    Error = 4,
}

Level 是冗余级别。数值越大越安静。

Variants

Unset = 0

排在 0 位：Config.log_level 的零值，语义为「保持默认」。

Debug = 1

派发/协商追踪（调试 MCP 时最有用）。

Info = 2

默认级别：启动通知、所选的模式。

Warn = 3

只留警告（被禁用的通道、未受保护的传输）。

Error = 4

只留错误诊断。

Implementations

impl Level

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

Trait Implementations

impl Clone for Level

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Level

impl Debug for Level

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

Formats the value using the given formatter.

impl Default for Level

fn default() -> Self

Returns the “default value” for a type.

impl Eq for Level

impl Ord for Level

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Level

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Level

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
