Trait ScanInput 

pub trait ScanInput<'a>:
    'a
    + Sized
    + Clone {
    type ScanCursor: ScanCursor<'a>;
    type StrCompare: StrCompare;

    // Required methods
    fn as_str(&self) -> &'a str;
    fn from_subslice(&self, subslice: &'a str) -> Self;
    fn to_cursor(&self) -> Self::ScanCursor;
}

This trait is the interface scanners use to access the input being scanned.

Required Associated Types

type ScanCursor: ScanCursor<'a>

Corresponding cursor type.

type StrCompare: StrCompare

Marker type used to do string comparisons.

Required Methods

fn as_str(&self) -> &'a str

Get the contents of the input as a string slice.

fn from_subslice(&self, subslice: &'a str) -> Self

Create a new input from a subslice of this input’s contents.

This should be used to ensure that additional state and settings (such as the string comparison marker) are preserved.

fn to_cursor(&self) -> Self::ScanCursor

Turn the input into an independent cursor, suitable for feeding back into a user-facing scanning macro.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementations on Foreign Types

impl<'a> ScanInput<'a> for &'a str

This implementation is provided to allow scanners to be used manually with a minimum of fuss.

It only supports direct, exact equality comparison.

type ScanCursor = StrCursor<'a>

type StrCompare = ExactCompare

fn as_str(&self) -> &'a str

fn from_subslice(&self, subslice: &'a str) -> Self

fn to_cursor(&self) -> Self::ScanCursor

Implementors

impl<'a, Cmp, Space, Word> ScanInput<'a> for StrCursor<'a, Cmp, Space, Word>

where Cmp: StrCompare, Space: SkipSpace, Word: SliceWord,

type ScanCursor = StrCursor<'a, Cmp, Space, Word>

type StrCompare = Cmp
