Struct Builder

Source
pub struct Builder { /* private fields */ }
Available on crate feature log-tracer only.
Expand description

Configures a new LogTracer.

Implementationsยง

Sourceยง

impl Builder

Source

pub fn new() -> Self

Returns a new Builder to construct a LogTracer.

Source

pub fn with_max_level(self, filter: impl Into<LevelFilter>) -> Self

Sets a global maximum level for log records.

Log records whose level is more verbose than the provided level will be disabled.

By default, all log records will be enabled.

Source

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

Configures the LogTracer to ignore all log records whose target starts with the given string.

This should be used when a crate enables the tracing/log feature to emit log records for tracing events. Otherwise, those events will be recorded twice.

Source

pub fn ignore_all<I>(self, crates: impl IntoIterator<Item = I>) -> Self
where I: Into<String>,

Configures the LogTracer to ignore all log records whose target starts with any of the given the given strings.

This should be used when a crate enables the tracing/log feature to emit log records for tracing events. Otherwise, those events will be recorded twice.

Source

pub fn init(self) -> Result<(), SetLoggerError>

Available on crate feature std only.

Constructs a new LogTracer with the provided configuration and sets it as the default logger.

Setting a global logger can only be done once.
