Struct SmilesErrorWithSpan 

pub struct SmilesErrorWithSpan { /* private fields */ }

Wraps the Smiles error adding the location of where the error was found

Implementations

impl SmilesErrorWithSpan

pub fn new(smiles_error: SmilesError, start: usize, end: usize) -> Self

Creates a new error from the SmilesError and the span

Examples

use smiles_rs::{SmilesError, SmilesErrorWithSpan};

let err = SmilesErrorWithSpan::new(SmilesError::UnexpectedEndOfString, 2, 3);
assert_eq!(err.start(), 2);
assert_eq!(err.end(), 3);

pub fn smiles_error(&self) -> SmilesError

Returns the SmilesError

Examples

use smiles_rs::{SmilesError, SmilesErrorWithSpan};

let err = SmilesErrorWithSpan::new(SmilesError::InvalidNumber, 0, 1);
assert_eq!(err.smiles_error(), SmilesError::InvalidNumber);

pub fn start(&self) -> usize

Returns the start of the span

Examples

use smiles_rs::{SmilesError, SmilesErrorWithSpan};

let err = SmilesErrorWithSpan::new(SmilesError::InvalidClass, 4, 6);
assert_eq!(err.start(), 4);

pub fn end(&self) -> usize

Returns the end of the span

Examples

use smiles_rs::{SmilesError, SmilesErrorWithSpan};

let err = SmilesErrorWithSpan::new(SmilesError::InvalidClass, 4, 6);
assert_eq!(err.end(), 6);

pub fn span(&self) -> Range<usize>

Returns the full span for the error

Examples

use smiles_rs::{SmilesError, SmilesErrorWithSpan};

let err = SmilesErrorWithSpan::new(SmilesError::UnexpectedLeftBracket, 1, 2);
assert_eq!(err.span(), 1..2);

pub fn render(&self, input: &str) -> String

Render the error pointing back to location in the original string

Examples

use smiles_rs::{SmilesError, SmilesErrorWithSpan};

let err = SmilesErrorWithSpan::new(SmilesError::UnexpectedRightBracket, 1, 2);
let rendered = err.render("C]");

assert!(rendered.contains("C]"));
assert!(rendered.contains("^"));
