Struct DiagnosticFilterNode

pub struct DiagnosticFilterNode {
    pub inner: DiagnosticFilter,
    pub parent: Option<Handle<DiagnosticFilterNode>>,
}

Represents a single parent-linking node in a tree of DiagnosticFilters backed by a crate::Arena.

A single element of a tree of diagnostic filter rules stored in crate::Module::diagnostic_filters. When nodes are built by a front-end, module-applicable filter rules are chained together in runs based on parse site. For instance, given the following:

• Module-applicable rules a and b.
• Rules c and d, applicable to an entry point called c_and_d_func.
• Rule e, applicable to an entry point called e_func.

The tree would be represented as follows:

a <- b
     ^
     |- c <- d
     |
     \- e

…where:

• d is the first leaf consulted by validation in c_and_d_func.
• e is the first leaf consulted by validation in e_func.

Fields

inner: DiagnosticFilter

parent: Option<Handle<DiagnosticFilterNode>>

Implementations

impl DiagnosticFilterNode

pub(crate) fn search( node: Option<Handle<Self>>, arena: &Arena<Self>, triggering_rule: StandardFilterableTriggeringRule, ) -> Severity

Finds the most specific filter rule applicable to triggering_rule from the chain of diagnostic filter rules in arena, starting with node, and returns its severity. If none is found, return the value of StandardFilterableTriggeringRule::default_severity.

When triggering_rule is not applicable to this node, its parent is consulted recursively.
