Struct DecodeLimits 

pub struct DecodeLimits {
    pub max_input_bytes: usize,
    pub max_tokens: usize,
    pub max_expr_nodes: usize,
    pub max_depth: usize,
    pub max_string_bytes: usize,
    pub max_blob_bytes: usize,
    pub max_collection_len: usize,
    pub max_trivia_items: usize,
}

Resource ceiling shared by every codec decode path.

These bounds are applied to untrusted input before bulk allocation where possible. They are deliberately generous for normal data and only reject pathological input.

Fields

max_input_bytes: usize

Maximum total input size, in bytes.

max_tokens: usize

Maximum number of tokens the decoder may produce.

max_expr_nodes: usize

Maximum number of Expr nodes in the decoded result.

max_depth: usize

Maximum nesting depth.

max_string_bytes: usize

Maximum length of a single decoded string, in bytes.

max_blob_bytes: usize

Maximum length of a single decoded byte blob.

max_collection_len: usize

Maximum length of a single decoded collection (list, vector, map, set).

max_trivia_items: usize

Maximum number of trivia items (comments, whitespace) retained.

Trait Implementations

impl Clone for DecodeLimits

fn clone(&self) -> DecodeLimits

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DecodeLimits

impl Debug for DecodeLimits

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

Formats the value using the given formatter.

impl Default for DecodeLimits

fn default() -> Self

Returns the “default value” for a type.

impl Eq for DecodeLimits

impl PartialEq for DecodeLimits

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