Struct partiql_source_map::location::Located

pub struct Located<T, Loc: Display> {
    pub inner: T,
    pub location: Location<Loc>,
}

A wrapper type that holds an inner value and a location for it

Fields

inner: T

The item that has a location attached

location: Location<Loc>

The location of the error

Implementations

impl<T, Loc: Display> Located<T, Loc>

pub fn map_loc<F, Loc2>(self, tx: F) -> Located<T, Loc2>where Loc2: Display, F: FnMut(Loc) -> Loc2,

Maps an Located<T, Loc> to Located<T, Loc2> by applying a function to the contained location and moving the contained inner

Example

assert_eq!("blah".to_string()
                .to_located(BytePosition::from(5)..BytePosition::from(10))
                .map_loc(|BytePosition(o)| BytePosition(o+5)),
            Located{
                inner: "blah".to_string(),
                location: (BytePosition(ByteOffset(10))..BytePosition(ByteOffset(15))).into()
            });

Trait Implementations

impl<T: Clone, Loc: Clone + Display> Clone for Located<T, Loc>

fn clone(&self) -> Located<T, Loc>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug, Loc: Debug + Display> Debug for Located<T, Loc>

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

Formats the value using the given formatter.

impl<T: Hash, Loc: Hash + Display> Hash for Located<T, Loc>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T: PartialEq, Loc: PartialEq + Display> PartialEq<Located<T, Loc>> for Located<T, Loc>

fn eq(&self, other: &Located<T, Loc>) -> bool

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

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
