Struct MaxScalarLength 

pub struct MaxScalarLength(pub usize);

Cap the byte length of any individual scalar.

Counts the raw scalar text, not the post-resolution value; numeric / boolean scalars are measured by their source representation. Helpful for resource-constrained pipelines that cannot trust upstream input size.

Examples

use noyalib::policy::MaxScalarLength;
use noyalib::{from_str_with_config, ParserConfig, Value};
let cfg = ParserConfig::new().with_policy(MaxScalarLength(8));
let ok: Value = from_str_with_config("k: short\n", &cfg).unwrap();
assert!(matches!(ok, Value::Mapping(_)));
let long: Result<Value, _> =
    from_str_with_config("k: this-is-too-long\n", &cfg);
assert!(long.is_err());

Trait Implementations

impl Clone for MaxScalarLength

fn clone(&self) -> MaxScalarLength

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MaxScalarLength

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

Formats the value using the given formatter.

impl Policy for MaxScalarLength

fn check_event(&self, event: PolicyEvent<'_>) -> Result<()>

Inspect a parser event during loading. Return Err(...) to abort the parse with a diagnostic.

fn check_value(&self, _value: &Value) -> Result<()>

Inspect the fully-built Value tree. Runs after the AST is assembled and before deserialisation continues. Return Err(...) to reject the document.
