source · pub struct Error { /* private fields */ }
Expand description
This type represents all possible errors that can occur when serializing or deserializing JSON data.
Implementations§
source§impl Error
impl Error
sourcepub fn line(&self) -> usize
pub fn line(&self) -> usize
One-based line number at which the error was detected.
Characters in the first line of the input (before the first newline character) are in line 1.
sourcepub fn column(&self) -> usize
pub fn column(&self) -> usize
One-based column number at which the error was detected.
The first character in the input and any characters immediately following a newline character are in column 1.
Note that errors may occur in column 0, for example if a read from an IO stream fails immediately following a previously read newline character.
sourcepub fn classify(&self) -> Category
pub fn classify(&self) -> Category
Categorizes the cause of this error.
Category::Io
- failure to read or write bytes on an IO streamCategory::Syntax
- input that is not syntactically valid JSONCategory::Data
- input data that is semantically incorrectCategory::Eof
- unexpected end of the input data
sourcepub fn is_io(&self) -> bool
pub fn is_io(&self) -> bool
Returns true if this error was caused by a failure to read or write bytes on an IO stream.
sourcepub fn is_syntax(&self) -> bool
pub fn is_syntax(&self) -> bool
Returns true if this error was caused by input that was not syntactically valid JSON.

EOF errors are turned into UnexpectedEof
IO errors.
