Struct kailua_env::Pos

pub struct Pos { /* fields omitted */ }

A position in the originating Source.

The position is composed of the Unit and an offset to the corresponding source. An offset ranges from 0 to the length of that source (inclusive). The actual meaning of the offset is resolved by Source; it can be either a byte offset or a two-byte word offset (for the FFI compatibility). The "source-independent" units have no corresponding source and the offset is always zero.

Trait Implementations

impl Copy for Pos

impl Clone for Pos

fn clone(&self) -> Pos

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq for Pos

fn eq(&self, __arg_0: &Pos) -> bool

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

fn ne(&self, __arg_0: &Pos) -> bool

This method tests for !=.

impl Eq for Pos

impl PartialOrd for Pos

fn partial_cmp(&self, __arg_0: &Pos) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, __arg_0: &Pos) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, __arg_0: &Pos) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, __arg_0: &Pos) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, __arg_0: &Pos) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Ord for Pos

fn cmp(&self, __arg_0: &Pos) -> Ordering

This method returns an Ordering between self and other.

impl Hash for Pos

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the given [Hasher].

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

Feeds a slice of this type into the given [Hasher].

impl Debug for Pos

In the debugging output the position is denoted @_ or @unit/off. It is only displayed when the alternate flag is enabled.

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

Formats the value using the given formatter.
