Function minify_html::with_friendly_error [−][src]
pub fn with_friendly_error(
code: &mut [u8],
cfg: &Cfg
) -> Result<usize, FriendlyError>
Minifies a slice in-place and returns the new minified length. Any original code after the end of the minified code is left intact.
This function is identical to in_place
except it returns a FriendlyError
on error instead.
FriendlyError
has a code_context
field, which is a string of a visual representation of the
source, with line numbers and position markers to aid in debugging syntax.
Arguments
code
- A mutable slice of bytes representing the source code to minify.cfg
- Configuration object to adjust minification approach.
Examples
use minify_html::{Cfg, FriendlyError, with_friendly_error}; let mut code = b"<p></div>".to_vec(); let cfg = &Cfg { minify_js: false, minify_css: false, }; match with_friendly_error(&mut code, cfg) { Ok(minified_len) => {} Err(FriendlyError { position, message, code_context }) => { assert_eq!(position, 3); assert_eq!(message, "Unexpected closing tag."); assert_eq!(code_context, concat!( "1|<p></div>\n", ">| R \n", )); } };
