Enum SimpleFillerError 

pub enum SimpleFillerError {
    NoSuchKey,
    WriteFailed(Error),
}

A convenient error type for fillers; you might even like to use it yourself.

You could also use (), but this gives you From<core::fmt::Error> so that you can use write!(out, …)?, and sane core::fmt::Display and std::error::Error implementations.

Variants

NoSuchKey

The map didn’t contain the requested key.

WriteFailed(Error)

Some fmt::Write operation returned an error.

Trait Implementations

impl Clone for SimpleFillerError

fn clone(&self) -> SimpleFillerError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SimpleFillerError

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

Formats the value using the given formatter.

impl Display for SimpleFillerError

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

Formats the value using the given formatter.

impl Error for SimpleFillerError

Available on crate feature std only.

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<K, V, W> Filler<W, SimpleFillerError> for &BTreeMap<K, V>

where K: Borrow<str> + Ord, V: AsRef<str>, W: Write,

Available on crate feature alloc only.

fn fill(&mut self, output: &mut W, key: &str) -> Result<(), SimpleFillerError>

Fill the value for the given key into the output string.

impl<K, V, W> Filler<W, SimpleFillerError> for &HashMap<K, V>

where K: Borrow<str> + Eq + Hash, V: AsRef<str>, W: Write,

Available on crate feature std only.

fn fill(&mut self, output: &mut W, key: &str) -> Result<(), SimpleFillerError>

Fill the value for the given key into the output string.

impl From<Error> for SimpleFillerError

fn from(e: Error) -> Self

Converts to this type from the input type.

impl PartialEq for SimpleFillerError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
