Enum FillError 

pub enum FillError {
    EndGroupOverflow {
        start_group: u64,
        delta: u64,
    },
    NotAFillParameter(u64),
    RepeatedFillParameter(u64),
    MalformedValue {
        key: u64,
        detail: &'static str,
    },
    NotRoundTrippable(String),
}

Errors from building a LOCATION_FILTER or a FILL_PARAMETERS value.

Variants

EndGroupOverflow

StartGroup + EndGroupDelta left the number space.

Section 5.1.2: “If StartGroup + EndGroupDelta exceeds 2^64 - 1, the endpoint MUST close the session with a PROTOCOL_VIOLATION.” A value the peer must close the session over is not a value this endpoint has a way of sending, so it is refused here instead.

Fields

start_group: u64

The start group the filter named.

delta: u64

The delta added to it.

NotAFillParameter(u64)

A parameter type Table 6 does not list was put inside FILL_PARAMETERS.

Section 10.2.15: “An endpoint that receives a parameter inside FILL_PARAMETERS that is not listed above MUST close the session with PROTOCOL_VIOLATION.”

RepeatedFillParameter(u64)

The same parameter type was put inside FILL_PARAMETERS twice where its own definition does not allow repeats.

MalformedValue

A value whose shape does not match the type it was filed under.

Fields

key: u64

The parameter type.

detail: &'static str

What is wrong with the value.

NotRoundTrippable(String)

The value this module built is one the codec’s own decoder refuses.

Unreachable unless the encoder here and the decoder in moqtap-codec have drifted apart, which is what the check exists to catch: a value that goes out and comes back as a session close is worse than one that never goes out.

Trait Implementations

impl Debug for FillError

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

Formats the value using the given formatter.

impl Display for FillError

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

Formats the value using the given formatter.

impl Eq for FillError

impl Error for FillError

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<FillError> for EndpointError

fn from(source: FillError) -> Self

Converts to this type from the input type.

impl PartialEq for FillError

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

Equality operator ==.

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

Inequality operator !=.
