Struct JsonValidator 

pub struct JsonValidator { /* private fields */ }

JSON validator with configurable constraints.

Handles incremental/streaming validation of JSON payloads and maintains internal state between chunk validations.

Instances should be created using JsonValidatorBuilder.

Implementations

impl JsonValidator

pub fn validate_chunk( &mut self, chunk: &[u8], end_of_stream: bool, ) -> Result<ValidationResult, ValidationError>

Validates a JSON chunk incrementally

This method can be called multiple times with different chunks of the same JSON. The validator maintains internal state to handle incremental validation and UTF-8 boundaries.

Arguments

• chunk - Bytes chunk to validate. Can be a fragment of the complete JSON.
• end_of_stream - true if this is the last chunk of the stream, false if there are more chunks pending.

Returns

• Ok(ValidationResult::Incomplete) - The chunk is valid but the JSON is incomplete. validate_chunk() should be called again with the next chunk.
• Ok(ValidationResult::Complete) - The JSON is complete and valid (only when end_of_stream = true).
• Err(ValidationError) - Validation error (invalid JSON or constraint violation).

pub fn reset(&mut self)

Resets the validator state to start a new validation
