Struct Filter 

pub struct Filter {
    pub min_level: Option<LogLevel>,
    pub component: Option<String>,
    pub attribute: Option<(String, Value)>,
}

Filter criteria applied to each record as it streams past.

Fields

min_level: Option<LogLevel>

Minimum log level (inclusive). Records below this level are dropped.

component: Option<String>

Optional component name. Only records with this exact component value pass.

attribute: Option<(String, Value)>

Optional (key, value) attribute match. Only records whose attributes map contains this exact pairing pass.

Implementations

impl Filter

pub const fn new() -> Self

Construct a filter that lets every record through.

pub const fn min_level(self, level: LogLevel) -> Self

Set the minimum severity.

pub fn component(self, component: impl Into<String>) -> Self

Restrict to a single component.

pub fn attribute(self, key: impl Into<String>, value: Value) -> Self

Restrict to records carrying a specific attribute key/value.

pub fn matches(&self, record: &Log) -> bool

Does this record satisfy every active criterion?

impl Clone for Filter

fn clone(&self) -> Filter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Filter

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

Formats the value using the given formatter.

impl Default for Filter

fn default() -> Filter

Returns the “default value” for a type.
