[−][src]Struct serde_lexpr::error::Error
This type represents all possible errors that can occur when serializing or deserializing S-expression data.
Methods
impl Error
[src]
pub fn location(&self) -> Option<Location>
[src]
Location of the error in the input stream.
pub fn classify(&self) -> Category
[src]
Categorizes the cause of this error.
Category::Io
- failure to read or write bytes on an IO streamCategory::Syntax
- input that is not a syntactically valid S-expressionCategory::Data
- input data that is semantically incorrectCategory::Eof
- unexpected end of the input data
Trait Implementations
impl From<Error> for Error
[src]
fn from(l: Error) -> Self
[src]
Convert a serde_lexpr::Error
into an io::Error
.
S-expression syntax errors are turned into InvalidData
IO errors. EOF
errors are turned into UnexpectedEof
IO errors.
use std::io; enum MyError { Io(io::Error), Lexpr(serde_lexpr::Error), } impl From<serde_lexpr::Error> for MyError { fn from(err: serde_lexpr::Error) -> MyError { use serde_lexpr::error::Category; match err.classify() { Category::Io => { MyError::Io(err.into()) } Category::Syntax | Category::Eof | Category::Data => { MyError::Lexpr(err) } } } }

[src]
fn invalid_type(unexp: Unexpected, exp: &dyn Expected) -> Self
[src]
fn invalid_value(unexp: Unexpected, exp: &dyn Expected) -> Self
[src]
Raised when a Deserialize
receives a value of the right type but that is wrong for some other reason. Read more
fn invalid_length(len: usize, exp: &dyn Expected) -> Self
[src]
Raised when deserializing a sequence or map and the input data contains too many or too few elements. Read more
fn unknown_variant(variant: &str, expected: &'static [&'static str]) -> Self
[src]
Raised when a Deserialize
enum type received a variant with an unrecognized name. Read more
fn unknown_field(field: &str, expected: &'static [&'static str]) -> Self
[src]
Raised when a Deserialize
struct type received a field with an unrecognized name. Read more
fn missing_field(field: &'static str) -> Self
[src]
Raised when a Deserialize
struct type expected to receive a required field with a particular name but that field was not present in the input. Read more
fn duplicate_field(field: &'static str) -> Self
[src]
Raised when a Deserialize
struct type received more than one of the same field. Read more
