Struct Error 

pub struct Error(/* private fields */);

Nostr database error.

Implementations

impl Error

pub fn new<E>(kind: ErrorKind, error: E) -> Self

where E: Into<Box<dyn Error + Send + Sync>>,

Creates a new error from a kind and an arbitrary error payload.

The payload is preserved as the error source, and its display output is captured as the error message.

pub const fn simple(kind: ErrorKind) -> Self

Creates an error without a specific message or source.

pub const fn with_static_message(kind: ErrorKind, message: &'static str) -> Self

Creates an error with a static message.

pub const fn kind(&self) -> ErrorKind

where ErrorKind: Copy,

Returns the error kind.

impl Error

pub fn storage<E>(error: E) -> Self

where E: Into<Box<dyn Error + Send + Sync>>,

Storage error

pub fn io<E>(error: E) -> Self

where E: Into<Box<dyn Error + Send + Sync>>,

I/O error

pub fn migration<E>(error: E) -> Self

where E: Into<Box<dyn Error + Send + Sync>>,

Migration error

pub const fn unsupported(message: &'static str) -> Self

unsupported feature

pub fn other<E>(error: E) -> Self

where E: Into<Box<dyn Error + Send + Sync>>,

Other error

Trait Implementations

impl Debug for Error

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

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
