Struct LimitsConfig 

#[non_exhaustive]
pub struct LimitsConfig {
    pub max_query_bytes: usize,
    pub max_nesting: usize,
    pub max_depth: usize,
    pub max_aliases: usize,
    pub max_root_fields: usize,
    pub max_fields: usize,
    pub max_directives: usize,
    pub max_complexity: usize,
}

Static analysis limits enforced on every document before it executes.

0 means “unlimited” for every field. The defaults admit any realistic application query while refusing the pathological shapes used to exhaust a GraphQL server (deep nesting, alias amplification, fragment fan-out).

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

max_query_bytes: usize

Largest accepted document, in bytes.

max_nesting: usize

Deepest lexical nesting of {, ( and [, checked before parsing so the parser itself is never handed a stack-exhausting input.

max_depth: usize

Deepest selection-set nesting of the executed operation, with fragments expanded. { a { b } } has depth 2.

max_aliases: usize

Most aliased fields in the executed operation, with fragments expanded.

max_root_fields: usize

Most fields selected directly on the operation’s root type.

max_fields: usize

Most field selections in the executed operation after fragment expansion — the guard against fragment fan-out (“fragment bombs”).

max_directives: usize

Most directives in the document.

max_complexity: usize

Schema-level complexity limit, applied when the plugin builds the schema itself (GraphqlPlugin::from_builder). Uses async-graphql’s #[graphql(complexity = ..)] cost model. 0 disables it.
