SettingsError

rama::http::proto::h3

Enum SettingsError 

pub enum SettingsError {
    Duplicate(SettingId),
    Forbidden(SettingId),
    TooMany,
    Malformed,
}
Available on crate features http and std only.
Expand description

An error encountered while validating or decoding HTTP/3 settings (RFC 9114 §7.2.4.1).

Duplicate and forbidden identifiers map to H3_SETTINGS_ERROR; malformed frame layout maps to H3_FRAME_ERROR (RFC 9114 §7.1), and exceeding a local budget maps to H3_EXCESSIVE_LOAD.

Variants§

§

Duplicate(SettingId)

The same identifier appeared twice (including unknown identifiers).

§

Forbidden(SettingId)

An HTTP/2-forbidden identifier (0x00, 0x02–0x05) was present.

§

TooMany

More entries than the configured budget.

§

Malformed

The payload was truncated or otherwise not a valid identifier/value sequence.
