Struct rxml::LexerOptions

pub struct LexerOptions {
    pub max_token_length: usize,
}

Hold options to configure a Lexer.

See also Lexer::with_options().

Fields

max_token_length: usize

Maximum number of bytes which can form a token.

This exists to limit the memory use of the Lexer for tokens where the data needs to be buffered in memory (most notably Token::Text and Token::AttributeValue).

If token data exceeds this limit, it depends on the token type whether a partial token is emitted or the lexing fails with Error::RestrictedXml: Text tokens are split and emitted in parts (and lexing continues), all other tokens exceeding this limit will cause an error.

Implementations

impl LexerOptions

pub fn defaults() -> LexerOptions

👎 Deprecated since 0.4.0:

use the Default trait implementation instead

Constructs default lexer options.

The defaults are implementation-defined and should not be relied upon.

pub fn max_token_length(self, v: usize) -> LexerOptions

Set the LexerOptions::max_token_length value.

Example

use rxml::{Lexer, LexerOptions};
let mut lexer = Lexer::with_options(LexerOptions::default().max_token_length(1024));
