pub struct LocalityContext {
pub region: Option<String>,
pub zone: Option<String>,
}Expand description
DW-094 (Ent): the edge’s locality context — its region and zone.
Threaded into the balancer at request time to enable locality-aware
endpoint selection. When both region and zone are None, the
balancer skips locality filtering (the OSS behavior).
The context is set from EdgeState.labels (the region and zone
keys) when running as an edge, or from the DWARA_REGION/
DWARA_ZONE environment variables in embedded mode.
Fields§
§region: Option<String>The edge’s region (e.g. us-east-1).
zone: Option<String>The edge’s zone (e.g. us-east-1a).
Implementations§
Source§impl LocalityContext
impl LocalityContext
Sourcepub fn new(region: Option<String>, zone: Option<String>) -> Self
pub fn new(region: Option<String>, zone: Option<String>) -> Self
Create a new locality context.
Sourcepub fn is_set(&self) -> bool
pub fn is_set(&self) -> bool
Whether locality-aware routing should be applied (at least one of region/zone is set).
Sourcepub fn region_matches(&self, endpoint_region: Option<&str>) -> bool
pub fn region_matches(&self, endpoint_region: Option<&str>) -> bool
Whether an endpoint region matches this context’s region. An endpoint with no region is always a match (locality-agnostic).
Sourcepub fn zone_matches(&self, endpoint_zone: Option<&str>) -> bool
pub fn zone_matches(&self, endpoint_zone: Option<&str>) -> bool
Whether an endpoint zone matches this context’s zone. An endpoint with no zone is always a match (zone-agnostic).
