Implementations

impl Tab

fn signal(self) -> &'static str

fn free_text(self) -> Option<&'static str>

Where a filter word with no operator goes.

Someone who types refused means “show me the ones that say refused”, which is what every log viewer in the market does with a bare word and what this one used to do with it: nothing at all, silently, while the filter bar showed the word and the rows looked filtered.

None for metrics, whose where terms are attribute predicates on data points — there is no text column to search, so a bare word there is reported rather than invented a meaning for.

fn fields(self) -> &'static [&'static str]

Columns of the signal’s root table.

This is what decides whether name=checkout filters a column or an attribute, and getting it wrong is silent both ways: an unknown field matches nothing rather than erroring, and a column missing from this list is sent as attr, which the Bloom filter prunes to zero rows. That is what happened to event_name, added to the schema after this list was written — so tests::the_field_list_is_the_schema now pins the two together. Not an intra-doc link: the target is behind cfg(test), so it does not exist in the configuration rustdoc builds.

Trait Implementations

impl Clone for Tab

fn clone(&self) -> Tab

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Tab

impl Debug for Tab

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

Formats the value using the given formatter.

impl Eq for Tab

impl PartialEq for Tab

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