Enum ConfigError 

pub enum ConfigError {
    InvalidRingSize(usize),
    InvalidShardCount(usize),
    SegmentTooSmall(u64),
    ContentTooLarge(usize),
    ZeroIndexStride,
    HashChainRequiresSingleShard {
        shards: usize,
    },
}

Errors that can occur while validating a Config.

Returned by Config::validate. Structured (rather than a String) so callers can react to a specific misconfiguration. Each variant carries the offending value.

Variants

InvalidRingSize(usize)

ring_size is not a power of two or is below 16.

InvalidShardCount(usize)

shards is outside [1, 256].

SegmentTooSmall(u64)

segment_size is below the 1MB minimum.

ContentTooLarge(usize)

max_content_size is above the 64MB ceiling.

ZeroIndexStride

index_stride is zero.

HashChainRequiresSingleShard

hash-chain requires a single shard (a global chain needs single-shard order). Only present under the hash-chain feature.

Fields

shards: usize

The offending shard count.

Trait Implementations

impl Clone for ConfigError

fn clone(&self) -> ConfigError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConfigError

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

Formats the value using the given formatter.

impl Display for ConfigError

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

Formats the value using the given formatter.

impl Eq for ConfigError

impl Error for ConfigError

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<ConfigError> for OpenError

fn from(source: ConfigError) -> Self

Converts to this type from the input type.

impl PartialEq for ConfigError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
