Struct wasmer_interface_types_fl::decoders::wat::Error
source · pub struct Error { /* private fields */ }
Expand description
A convenience error type to tie together all the detailed errors produced by this crate.
This type can be created from a lexer::LexError
or [parser::Error
].
This also contains storage for file/text information so a nice error can be
rendered along the same lines of rustc’s own error messages (minus the
color).
This type is typically suitable for use in public APIs for consumers of this crate.
Implementations§
source§impl Error
impl Error
sourcepub fn new(span: Span, message: String) -> Error
pub fn new(span: Span, message: String) -> Error
Creates a new error with the given message
which is targeted at the
given span
Note that you’ll want to ensure that set_text
or set_path
is called
on the resulting error to improve the rendering of the error message.
sourcepub fn set_text(&mut self, contents: &str)
pub fn set_text(&mut self, contents: &str)
To provide a more useful error this function can be used to extract relevant textual information about this error into the error itself.
The contents
here should be the full text of the original file being
parsed, and this will extract a sub-slice as necessary to render in the
Display
implementation later on.
