Struct codepage_437::IntoCp437Error
[−]
[src]
pub struct IntoCp437Error { /* fields omitted */ }
A possible error value when converting a String
into a cp437 byte vector.
This type is the error type for the into_cp437()
function on IntoCp437
. It is designed in such a way to carefully avoid reallocations:
the into_string()
function will give back the String that was used
in the conversion attempt.
The Cp437Error
type represents an error that may
occur when converting a &str
to a sequence of u8
s. In this sense, it's
an analogue to IntoCp437Error
, and you can get one from a IntoCp437Error
through the cp437_error()
function.
Examples
// some unrepresentable chracters, in a String let word = "Eżektor".to_string(); let value = word.into_cp437(&CP437_CONTROL); assert!(value.is_err()); assert_eq!(value.unwrap_err().into_string(), "Eżektor".to_string());
Methods
impl IntoCp437Error
[src]
pub fn as_str(&self) -> &str
[src]
Returns a &str
that was attempted to convert to cp437.
Examples
// some unrepresentable chracters, in a String let word = "Eżektor".to_string(); let value = word.into_cp437(&CP437_CONTROL); assert_eq!(value.unwrap_err().as_str(), "Eżektor");
pub fn into_string(self) -> String
[src]
Returns the String
that was attempted to convert to cp437.
This function is carefully constructed to avoid allocation. It will consume the error, moving out the string, so that a copy of the string does not need to be made.
Examples
// some unrepresentable chracters, in a String let word = "Eżektor".to_string(); let value = word.into_cp437(&CP437_CONTROL); assert_eq!(value.unwrap_err().into_string(), "Eżektor".to_string());
pub fn cp437_error(&self) -> Cp437Error
[src]
Fetch a Cp437Error
to get more details about the conversion failure.
The Cp437Error
type represents an error that may
occur when converting a &str
to a sequence of u8
s. In this sense, it's
an analogue to IntoCp437Error
. See its documentation for more details
on using it.
Examples
// some unrepresentable chracters, in a String let word = "Eżektor".to_string(); let error = word.into_cp437(&CP437_CONTROL).unwrap_err().cp437_error(); // the first character is unrepresentable here assert_eq!(error.representable_up_to, 1);
