Struct TurtleValidator 

pub struct TurtleValidator { /* private fields */ }

Line-oriented Turtle syntax validator.

Implementations

impl TurtleValidator

pub fn new() -> Self

Create a new validator in lenient mode.

pub fn strict(self) -> Self

Enable strict mode (additional warnings become errors).

pub fn validate(&self, input: &str) -> ValidationReport

Validate an entire Turtle document string.

pub fn validate_prefix_declaration(&self, line: &str) -> Option<ValidationIssue>

Validate a single @prefix or PREFIX declaration line.

Returns Some(Error) if the line is malformed.

pub fn validate_triple_line( &self, line: &str, known_prefixes: &[String], ) -> Option<ValidationIssue>

Validate a single non-prefix Turtle line.

Returns Some(Warning) for unknown prefixes, Some(Error) for unclosed angle brackets, etc.

pub fn validate_iri(&self, iri: &str) -> bool

Returns true when iri looks like a valid (absolute) IRI.

This is a heuristic check — it just verifies the IRI contains a scheme separator and no bare whitespace.

pub fn validate_prefix_name(&self, prefix: &str) -> bool

Returns true when prefix is a valid Turtle prefix name (PN_PREFIX).

A prefix name consists of letters, digits (after the first character), underscores, hyphens, and dots (but not as the last character).

pub fn count_triples_approx(input: &str) -> usize

Count the approximate number of triples in a Turtle document by counting statement-ending . tokens on non-comment lines.

impl Default for TurtleValidator

fn default() -> Self

Returns the “default value” for a type.
