Methods

`impl Token`
[src]

`fn is_like_gt(&self) -> bool`

Unstable (rustc_private)

Returns true if the token starts with '>'.

`fn can_begin_expr(&self) -> bool`

Unstable (rustc_private)

Returns true if the token can appear at the start of an expression.

`fn is_lit(&self) -> bool`

Unstable (rustc_private)

Returns true if the token is any literal

`fn is_ident(&self) -> bool`

Unstable (rustc_private)

Returns true if the token is an identifier.

`fn is_interpolated(&self) -> bool`

Unstable (rustc_private)

`fn is_strict_keyword(&self) -> bool`

Unstable (rustc_private)

Returns true if the token is a strict keyword.

`fn is_reserved_keyword(&self) -> bool`

Unstable (rustc_private)
