Struct serde_yaml::Error [−][src]
pub struct Error(_);
This type represents all possible errors that can occur when serializing or deserializing YAML data.
Methods
impl Error
[src]
impl Error
pub fn location(&self) -> Option<Location>
[src]
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);
