# Trait unicode_xid::UnicodeXID [−] [src]

    pub trait UnicodeXID {
        fn is_xid_start(self) -> bool;
        fn is_xid_continue(self) -> bool;
    }

Methods for determining if a character is a valid identifier character.

## Required Methods

### `fn is_xid_start(self) -> bool`

Returns whether the specified character satisfies the 'XID_Start' Unicode property.

'XID_Start' is a Unicode Derived Property specified in UAX #31, mostly similar to ID_Start but modified for closure under NFKx.

### `fn is_xid_continue(self) -> bool`

Returns whether the specified `char` satisfies the 'XID_Continue' Unicode property.

'XID_Continue' is a Unicode Derived Property specified in UAX #31, mostly similar to 'ID_Continue' but modified for closure under NFKx.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
