Struct AstConfig 

pub struct AstConfig {
    pub languages: Vec<AstConfigLanguage>,
    pub packs: Vec<AstLanguagePack>,
    pub semantic_false_positive_budget_pct: u8,
    pub semantic_min_confidence: u8,
}

Configuration for AST-aware merge via tree-sitter (§6.2).

Controls which languages use AST-level merge as a fallback when diff3 fails. Enabled by default for all built-in language packs.

[merge.ast]
languages = ["rust", "python", "typescript", "javascript", "go"]
packs = ["core", "web", "backend"]
semantic_false_positive_budget_pct = 5
semantic_min_confidence = 70

Fields

languages: Vec<AstConfigLanguage>

Languages for which AST merge is enabled.

Supported values: "rust", "python", "typescript", "javascript", "go". Empty by default; language packs control baseline enablement.

packs: Vec<AstLanguagePack>

Optional language packs that expand to multiple languages.

Packs are additive with languages and deduplicated by the merge layer.

semantic_false_positive_budget_pct: u8

Maximum allowed semantic false-positive rate percentage (0-100).

Semantic rules with confidence below min_confidence are downgraded to generic AST-node conflict reasons to keep diagnostics conservative.

semantic_min_confidence: u8

Minimum confidence required for semantic rule-specific diagnostics.

Trait Implementations

impl Clone for AstConfig

fn clone(&self) -> AstConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AstConfig

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

Formats the value using the given formatter.

impl Default for AstConfig

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AstConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for AstConfig

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