Enum miau::error::ErrorCode

pub enum ErrorCode {
    WrongNodeType(NodeType, NodeType),
    WrongValueType(String, String),
    IndexOutOfRange(usize),
    WrongKeyType(NodeType, String),
    KeyNotFound(String),
    BadNodeMerge(NodeType, NodeType),

}

Describes underlying cause of error.

Variants

WrongNodeType(NodeType, NodeType)

Informs that operation is not valid for given node type e.g descending into value node.

WrongValueType(String, String)

Informs that it is not possible to convert value present in configuration to desired type.

IndexOutOfRange(usize)

Informs that requested index from array kept in configuration exceeds bounds of the array.

WrongKeyType(NodeType, String)

Informs that key specified while accessing configuration is of wrong type. Might occur when trying to e.g index into map.

KeyNotFound(String)

Informs that requested key is not present in a configuration.

BadNodeMerge(NodeType, NodeType)

Informs about errors during merging configuration nodes. Might occur in circumstances like merging map node with array node.

IoError(Error)

Informs about different kinds of input/output errors. Occurs mostly during source collection e.g. reading file or downloading content over network.

DeserializationError(String)

Informs about errors during deserialization. It covers both external sources and internal structures deserialization.

EmptyConfiguration

Informs about error attributable to executing invalid operations on empty configuration.

NullValue

Informs about errors attributable to invalid operation on null value.

ParsingError(String)

Informs about parsing error that occured.

Trait Implementations

impl Debug for ErrorCode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ErrorCode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for ErrorCode

pub fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<ErrorCode> for ConfigurationError

fn from(e: ErrorCode) -> Self

Performs the conversion.
