# Struct url::ParseOptions [−] [src]

    pub struct ParseOptions<'a> { /* fields omitted */ }

Full configuration for the URL parser.

## Implementations

### `impl<'a> ParseOptions<'a>` [src]

#### `pub fn base_url(self, new: Option<&'a Url>) -> Self` [src]

Change the base URL

#### `pub fn encoding_override(self, new: EncodingOverride<'a>) -> Self` [src]

Override the character encoding of query strings. This is a legacy concept only relevant for HTML.

#### `pub fn syntax_violation_callback(
self,
new: Option<&'a dyn Fn(SyntaxViolation)>
) -> Self` [src]

Call the provided function or closure for a non-fatal `SyntaxViolation` when it occurs during parsing. Note that since the provided function is `Fn`, the caller might need to utilize interior mutability, such as with a `RefCell`, to collect the violations.

## Example

    use std::cell::RefCell;
    use url::{Url, SyntaxViolation};
    let violations = RefCell::new(Vec::new());
    let url = Url::options()
        .syntax_violation_callback(Some(&|v| violations.borrow_mut().push(v)))
        .parse("https:////example.com")?;
    assert_eq!(url.as_str(), "https://example.com/");
    assert_eq!(violations.into_inner(),
               vec!(SyntaxViolation::ExpectedDoubleSlash));

#### `pub fn parse(self, input: &str) -> Result<Url, ParseError>` [src]

Parse an URL string with the configuration so far.
