[−][src]Struct pcre2::Error
A PCRE2 error.
An error can occur during compilation or during matching. The kind of this error indicates the type of operation being performed when the error occurred.
Methods
impl Error
[src]
pub fn kind(&self) -> &ErrorKind
[src]
Return the kind of this error.
The kind indicates the type of operation that was attempted which resulted in this error.
pub fn code(&self) -> c_int
[src]
Return the raw underlying PCRE2 error code.
This can be useful if one needs to determine exactly which error
occurred, which can be done with case analysis over the constants
exported in the pcre2-sys
crate.
pub fn offset(&self) -> Option<usize>
[src]
Return the underlying offset associated with this error, if one exists.
The offset is typically only available for compile time errors, and is supposed to indicate the general position in the pattern where an error occurred.
