Enum FileDescriptorError 

pub enum FileDescriptorError {
    InvalidBudget {
        limit: usize,
    },
    ConfigurationConflict {
        configured: usize,
        requested: usize,
    },
    CapacityPolicyConflict {
        configured: bool,
        requested: bool,
    },
    BudgetExceeded {
        requested: usize,
        available: usize,
        limit: usize,
    },
    OsLimit {
        requested: usize,
        os_code: Option<i32>,
        soft: Option<u64>,
        hard: Option<u64>,
    },
}

Descriptor admission failures are distinct from corrupt storage or a busy branch. Project quota counts belong to one engine resource domain; OS-limit failures can additionally report the process allowance when it is known.

Trait Implementations

impl Clone for FileDescriptorError

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 FileDescriptorError

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

Formats the value using the given formatter.

impl Display for FileDescriptorError

Formats the value using the given formatter.

impl Eq for FileDescriptorError

impl Error for FileDescriptorError

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 PartialEq for FileDescriptorError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
