Struct RustCode

pub struct RustCode {
    pub module: &'static str,
    pub line: u32,
    pub column: u32,
    pub blame_fn: fn(&str),
}

A component of RustOrigin that indicates a specific location in the Rust source code.

Fields

module: &'static str

The name of the Rust module.

line: u32

A one-based line number within the module file.

column: u32

A one-based column number within a line of the module file.

blame_fn: fn(&str)

A function that panics at the location of the pointed Rust construct with the specified error message.

Implementations

impl RustCode

pub fn blame(&self, message: &str)

Similar to RustOrigin::blame. Refer to its documentation for details.

pub fn position(&self) -> Position

A helper function that returns a Position representation of the line and column of this RustCode.

pub fn span(&self) -> PositionSpan

A helper function that returns a zero-span Range of positions: code.position()..code.position().

pub fn span_string(&self) -> String

A helper function that formats the line and column in the canonical end-user-facing form of [<line>]:[<column>].

Trait Implementations

impl Clone for RustCode

fn clone(&self) -> RustCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RustCode

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

Formats the value using the given formatter.

impl Display for RustCode

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

Formats the value using the given formatter.

impl Hash for RustCode

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 RustCode

fn cmp(&self, other: &RustCode) -> 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,

Restrict a value to a certain interval.

impl PartialEq for RustCode

fn eq(&self, other: &Self) -> 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 RustCode

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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