Struct Position 

#[repr(transparent)]
pub struct Position {
    pub offset: u32,
}

Represents a specific byte offset within a single source file.

Fields

offset: u32

Implementations

impl Position

pub const fn new(offset: u32) -> Self

Creates a new Position from a byte offset.

pub const fn zero() -> Self

Creates a new Position with an offset of zero.

pub const fn is_zero(&self) -> bool

Checks if this position is at the start of a file.

pub const fn forward(&self, offset: u32) -> Self

Returns a new position moved forward by the given offset.

Uses saturating arithmetic to prevent overflow.

pub const fn backward(&self, offset: u32) -> Self

Returns a new position moved backward by the given offset.

Uses saturating arithmetic to prevent underflow.

pub const fn range_for(&self, length: u32) -> Range<u32>

Creates a Range<u32> starting at this position’s offset with a given length.

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Position

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

Formats the value using the given formatter.

impl From<&Position> for u32

fn from(position: &Position) -> u32

Converts to this type from the input type.

impl HasPosition for Position

fn position(&self) -> Position

Returns the source position.

fn offset(&self) -> u32

A convenience method to get the byte offset of the position.

impl Hash for Position

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 Ord for Position

fn cmp(&self, other: &Position) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

impl PartialEq for Position

fn eq(&self, other: &Position) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Sub<u32> for Position

type Output = Position

The resulting type after applying the - operator.

fn sub(self, rhs: u32) -> Self::Output

Performs the - operation.

impl SubAssign<u32> for Position

fn sub_assign(&mut self, rhs: u32)

Moves the position backward in-place.
