Struct Limits 

pub struct Limits {
    pub max_depth: usize,
    pub max_anchors: usize,
    pub max_document_size: usize,
    pub max_string_length: usize,
    pub max_alias_depth: usize,
    pub max_collection_size: usize,
    pub max_complexity_score: usize,
    pub max_total_alias_nodes: usize,
    pub timeout: Option<Duration>,
}

Resource limits configuration for YAML processing

Fields

max_depth: usize

Maximum nesting depth for collections

max_anchors: usize

Maximum number of anchors in a document

max_document_size: usize

Maximum document size in bytes

max_string_length: usize

Maximum string length in characters

max_alias_depth: usize

Maximum alias expansion depth

max_collection_size: usize

Maximum number of items in a collection

max_complexity_score: usize

Maximum complexity score (calculated based on structure)

max_total_alias_nodes: usize

Maximum total number of nodes materialized by alias expansion in one document. Closes the billion-laughs gap where wide alias fan-out allocates millions of nodes before max_complexity_score fires. The check runs before each alias clone so memory cannot blow up between the check and the materialization.

timeout: Option<Duration>

Timeout for parsing operations

Implementations
