Enum FrameError 

pub enum FrameError {
    MissingContentLength,
    InvalidContentLength(String),
    MalformedHeader(String),
    NonAsciiHeader,
    DuplicateContentLength,
    OverlargeMessage {
        got: u64,
        limit: u64,
    },
}

Header-parse failures.

Variants

MissingContentLength

Header block contained no Content-Length field. The LSP base protocol says it MUST be present; any message missing it is unframable.

InvalidContentLength(String)

Content-Length value didn’t parse as an unsigned integer.

MalformedHeader(String)

Header line lacked the name: value separator. ASCII only; whitespace around : is tolerated.

NonAsciiHeader

Header bytes were not valid ASCII (or the bytes before the body terminator weren’t, which forces a teardown).

DuplicateContentLength

Two Content-Length fields in the same header block. The LSP base protocol doesn’t say what to do; we reject. Forwarding the wrong length would either truncate the body or read past it into the next message.

OverlargeMessage

Content length exceeds the configured per-message ceiling. Defends against a malicious / runaway server pinning a gigabyte of memory per message.

Fields

got: u64

limit: u64

Trait Implementations

impl Debug for FrameError

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

Formats the value using the given formatter.

impl Display for FrameError

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

Formats the value using the given formatter.

impl Eq for FrameError

impl Error for FrameError

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<FrameError> for LspError

fn from(source: FrameError) -> Self

Converts to this type from the input type.

impl PartialEq for FrameError

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

Equality operator ==.

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

Inequality operator !=.
