Trait Implementations

impl<'b> Clone for Token<'b>

fn clone(&self) -> Token<'b>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'b> Debug for Token<'b>

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

Formats the value using the given formatter.

impl Display for Token<'_>

Pretty print a token.

Since we only show a single token we can not use diagnostic notation as in the Display impl of Tokenizer. Instead, the following syntax is used:

• Numeric values and booleans are displayed as in Rust. Floats are always shown in scientific notation.
• Text strings are displayed in double quotes.
• Byte strings are displayed in single quotes prefixed with h and hex-encoded, e.g. h'01 02 ef'.
• An array is displayed as A[n] where n denotes the number of elements. The following n tokens are elements of this array.
• A map is displayed as M[n] where n denotes the number of pairs. The following n tokens are entries of this map.
• Tags are displayed with T(t) where t is the tag number.
• Simple values are displayed as simple(n) where n denotes the numeric value.
• Indefinite items start with:
  • ?B[ for byte strings,
  • ?S[ for text strings,
  • ?A[ for arrays,
  • ?M[ for maps, and end with ] when a Token::Break is encountered. All tokens in between belong to the indefinite container.
• Token::Null is displayed as null and Token::Undefined as undefined.

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

Formats the value using the given formatter.

impl<'b> PartialEq<Token<'b>> for Token<'b>

fn eq(&self, other: &Token<'b>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Token<'b>) -> bool

This method tests for !=.
