Variants

InvalidBlockConfirmationDepth

Invalid block confirmation depth, it must be at least 2.

Fork blocks are only accepted above block offset block_confirmation_depth - 1, smaller values leave no block offset for them.

InvalidSoftConfirmationDepth

Invalid soft confirmation depth, it must be smaller than block confirmation depth

ReadRequestCancelled

Fields

error: Error

PageGroupSizeTooSmall

Page group size is too small, must be at least two pages

Fields

page_group_size: u32

Page group size in pages

PageGroupSizeTooLarge

Page group size is larger than the storage backend

Fields

page_group_size: u32

Trait Implementations

impl Debug for ClientDatabaseError

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

Formats the value using the given formatter.

impl Display for ClientDatabaseError

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

Formats the value using the given formatter.

impl Error for ClientDatabaseError

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.
