Struct FillError 

pub struct FillError { /* private fields */ }

A flattened terminal error for a fill: the node’s pull leg records why its pull ended, and the serve-side SessionOutboardReader / data reader surface it. A String message rather than anyhow::Error because the outcome must be Clone (every observer reads it) and anyhow::Error is not.

Implementations

impl FillError

pub fn new(msg: impl Into<String>) -> Self

Wrap a flattened terminal message.

pub fn held_bytes_cap(msg: impl Into<String>) -> Self

A fill that ended because storing more of its range would push the bytes this node holds for the blob past its max_blob_size cap. The node serves what it holds and refuses the rest, so a serve that reads past it ends as a refusal, not as a node fault.

pub const fn is_held_bytes_cap(&self) -> bool

Whether the fill ended at the cap on bytes held (Self::held_bytes_cap).

pub fn unlanded(&self, context: impl Into<String>) -> Error

The I/O error a serve read raises for bytes this ended fill did not land, prefixed by context. The fill’s error stays in the error’s source chain, so ended_at_held_bytes_cap finds it, and is_unlanded holds for it.

Trait Implementations

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.
