Variants

None

The token has no particular mask. This is the default situation. It may indicate that further processing can be done on a token.

Whitespace

the token represents a whitespace (in any shape or form)

Punctuation

the token represents punctuation (in any shape or form)

CJK

the token represents a single Chinese/Japanese/Korean character (including kana and hangul)

Special

the token is a special marker (such as a separator marker, a class marker, etc)

Begin

the token is the begin in a series of subtokens, the offset refers specifically to the subtoken. Subsequent tokens in this sequence will carry the 'Continuation' mask

Continuation

the token is the continuation of the previous token, the offset refers specifically to the subtoken. All but the first subtoken in a sequence carry this mask (the first carries 'Begin'). (this is the reverse of Mask::Unfinished)

Unfinished

the token is the start of a token but not finished yet. All but the last subtoken in the a token sequence carry this mask. This is the reverse of Mask::Continuation.

Unknown

The token is out of vocabulary, it is unknown by the tokenizer and it will decode to unknown. Tokens that can be decoded properly (but may still be out of vocabulary) should not set this.

Trait Implementations

impl Clone for Mask

fn clone(&self) -> Mask

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Mask

impl Debug for Mask

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

#[must_use]fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use]fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use]fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Mask

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.
