Enum PlanError 

pub enum PlanError {
    TargetTooSmallForMetadata {
        target: u64,
        reserved: u64,
    },
    TargetTooSmallForUserData {
        target: u64,
        user_bytes: u64,
    },
    UnsupportedBlockSize(u32),
    TargetNotBlockAligned(u64),
}

Errors the planner can return. Keeping these distinct from FilesystemError since the planner doesn’t do any I/O — every failure is an arithmetic / sizing issue surfaced as a string.

Trait Implementations

impl Clone for PlanError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PlanError

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

Formats the value using the given formatter.

impl Display for PlanError

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

Formats the value using the given formatter.

impl Error for PlanError

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.
