Enum tengwar::mode::ParseAction

pub enum ParseAction {
    MatchedNone,
    MatchedPart(usize),
    MatchedToken {
        token: Token,
        len: usize,
    },
    Skip(usize),
    Escape {
        len_seq: usize,
        n_skip: usize,
    },
}

The result of a call to TengwarMode::process. This specifies the next action that will be taken by a Tokenizer.

Variants

MatchedNone

Nothing could be done with the input.

MatchedPart(usize)

A portion of the input was processed successfully, but more is needed.

MatchedToken

Fields

token: Token

The completed Token.

len: usize

The number of chars that were processed during the final step of parsing this Token.

A complete Token has been processed.

Skip(usize)

A portion of the input has been determined to be irrelevant to the processing. The contained number of chars should be passed through unchanged.

Escape

Fields

len_seq: usize

The number of chars in the escape sequence itself. These will be ignored, and will not be present in the output in any way.

n_skip: usize

The number of chars affected by the escape sequence. These will be passed through to the output without being processed.

An escape sequence has been found. The next char will be ignored, and the one following will be passed through unchanged.

Implementations

pub const ESC_BACKSLASH: Self = _
