Struct serde_yaml::Error
source · pub struct Error(/* private fields */);
Expand description
An error that happened serializing or deserializing YAML data.
Implementations§
source§impl Error
impl Error
sourcepub fn location(&self) -> Option<Location>
pub fn location(&self) -> Option<Location>
Returns the Location from the error if one exists.
Not all types of errors have a location so this can return None
.
§Examples
// The `@` character as the first character makes this invalid yaml
let invalid_yaml: Result<Value, Error> = serde_yaml::from_str("@invalid_yaml");
let location = invalid_yaml.unwrap_err().location().unwrap();
assert_eq!(location.line(), 1);
assert_eq!(location.column(), 1);
