pub const RESOURCE_TYPE_WOULD_BLOCK: u8 = 255u8

pub fn hardware_error(component: u8, error_code: u16) -> Self

Creates a hardware error for embedded environments

pub fn internal(code: u32) -> Self

Creates an internal error with a specific error code

pub fn is_network_error(&self) -> bool

Returns true if this is a network-related error

pub fn is_capacity_error(&self) -> bool

Returns true if this is a capacity-related error

pub fn is_hardware_error(&self) -> bool

Returns true if this is a hardware-related error

pub const fn error_code(&self) -> u32

Returns a numeric error code for embedded environments

pub const fn error_category(&self) -> u32

Returns the error category (high nibble)

pub fn with_context<S: Into<String>>(self, context: S) -> Self

Adds additional context to an error (std only)

pub fn into_anyhow(self) -> Error

Converts this error into an anyhow::Error (std only)

Trait Implementations

impl Debug for DbError

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

Formats the value using the given formatter.

impl Display for DbError

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

Formats the value using the given formatter.

impl Error for DbError

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl From<DbError> for RemoteError

fn from(err: DbError) -> Self

Converts to this type from the input type.

impl From<Error> for DbError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for DbError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<ExecutorError> for DbError

Convert executor errors to database errors

This allows runtime adapters to return ExecutorError while the core database works with DbError for consistency across the API.

fn from(err: ExecutorError) -> Self

Converts to this type from the input type.
