Fields

max_age_secs: Option<u64>

Implementations

impl FieldLevelCacheDirective

pub fn parse(input: &str) -> Option<Self>

Parse a @cacheControl(maxAge: N, scope: "PUBLIC") directive string.

Returns None if the input does not contain @cacheControl.

pub fn effective_max_age_ms( directives: &[FieldLevelCacheDirective], ) -> Option<u64>

Compute the effective max_age_ms for a set of directives collected from all fields/types resolved during a query.

The effective value is the minimum maxAge across all directives that have an explicit maxAge. Returns None if no directive specifies maxAge.
