Enum Error

pub enum Error {
    NoRoot,
    InvalidRate,
    InvalidStructure,
}

Variants

NoRoot

First bucket passed to HTB::new must be a node with parent set to None

InvalidRate

Calculated flow rate is higher that what can fit into usize

flow rate is calculated using least common multiplier and if it is very small HTB ends up sing their product which can overflow. To fix this problem try to tweak the values to have bigger LCM. For example instead of using 881 and 883 (both are prime numbers) try using 882

InvalidStructure

Invalid config passed to HTB:

Buckets should be given in depth first search traversal order:

• root with parent set to None
• higher priority child of the root
• followed by high priority child of the child, if any, etc.
• followed by the next child

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<TryFromIntError> for Error

fn from(_: TryFromIntError) -> Self

Converts to this type from the input type.

impl Copy for Error
