Struct Diag 

pub struct Diag {
    pub line: usize,
    pub col: usize,
    pub end_line: usize,
    pub end_col: usize,
    pub severity: u8,
    pub msg: String,
}

a diagnostic of a code editor: a part of the text in lines and columns from 1 as compilers report them (columns count characters, a tab is one; the end is exclusive, an end at or before the start marks the one character at the start, past a line’s end the end of the line), a severity DIAG_* and the message (see the module header)

Fields

line: usize

where it starts (from 1)

col: usize

end_line: usize

where it ends (exclusive)

end_col: usize

severity: u8

DIAG_ERROR, DIAG_WARNING, DIAG_INFO

msg: String

Implementations

impl Diag

pub fn new( line: usize, col: usize, end_col: usize, severity: u8, msg: &str, ) -> Diag

a part of one line: line:col .. line:end_col

pub fn span( line: usize, col: usize, end_line: usize, end_col: usize, severity: u8, msg: &str, ) -> Diag

line:col .. end_line:end_col

impl Default for Diag

fn default() -> Self

Returns the “default value” for a type.
