Struct Problem 

pub struct Problem {
    pub start: usize,
    pub end: usize,
    pub severity: Severity,
    pub unnecessary: bool,
    pub message: String,
    pub source: Option<String>,
    pub code: Option<String>,
    pub docs: Option<String>,
}

One diagnostic, placed in the source by byte offsets.

Fields

start: usize

Never empty, and always covers at least one visible character, so there is always something to draw the squiggle under.

end: usize

severity: Severity

unnecessary: bool

Code that does nothing (an unused binding): drawn faded instead of squiggled.

message: String

source: Option<String>

code: Option<String>

docs: Option<String>

Where the code is explained.

Trait Implementations

impl Clone for Problem

fn clone(&self) -> Problem

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Problem

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

Formats the value using the given formatter.

impl PartialEq for Problem

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