Implementations

impl SourceInfo

pub const fn new(start: usize, len: usize) -> Self

Construct a new SourceInfo from a start offset and a length, in bytes.

pub const fn from_offset(offset: usize) -> Self

Construct a new zero-length SourceInfo pointing to a specific offset.

pub const fn range_start(&self) -> usize

Get the start of range, in bytes.

pub const fn range_end(&self) -> usize

Get the end of range, in bytes.

pub const fn len(&self) -> usize

Get the length of the source range, in bytes.

Panics

Panics if the end of the range is before the start.

pub const fn is_empty(&self) -> bool

Tests whether this SourceInfo range is a zero-length offset.

impl<'de> Deserialize<'de> for SourceInfo

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for SourceInfo

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 SourceInfo

fn cmp(&self, other: &Self) -> 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 + PartialOrd,

impl PartialEq for SourceInfo

fn eq(&self, other: &SourceInfo) -> 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.

impl PartialOrd for SourceInfo

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

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