Struct tokio_bin_process::event_matcher::EventMatcher

pub struct EventMatcher { /* private fields */ }

Use to check if an Event matches certain criteria.

Construct by chaining methods, e.g:

assert!(
    EventMatcher::new()
        .with_level(Level::Info)
        .with_target("module::internal_module")
        .with_message("Some message")
        .matches(event)
);

Implementations

impl EventMatcher

pub fn new() -> EventMatcher

Creates a new EventMatcher that by default matches any Event.

pub fn with_level(self, level: Level) -> EventMatcher

Sets the matcher to only match an Event when it has the exact provided level

pub fn with_target(self, target: &str) -> EventMatcher

Sets the matcher to only match an Event when it has the exact provided target

pub fn with_message(self, message: &str) -> EventMatcher

Sets the matcher to only match an Event when it has the exact provided message

pub fn with_count(self, count: Count) -> EventMatcher

Defines how many times the matcher must match to pass an assertion

This is not used internally i.e. it has no effect on EventMatcher::matches Instead its only used by higher level assertion logic.

pub fn matches(&self, event: &Event) -> bool

Returns true only if this matcher matches the passed Event
