Expand description

An object representing the method header to be matched.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Exact(String)

The exact method header to be matched on.

§

Prefix(String)

The specified beginning characters of the method header to be matched on.

§

Range(MatchRange)

An object that represents the range of values to match on. The first character of the range is included in the range, though the last character is not. For example, if the range specified were 1-100, only values 1-99 would be matched.

§

Regex(String)

The regex used to match the method header.

§

Suffix(String)

The specified ending characters of the method header to match on.

§

Unknown

The Unknown variant represents cases where new union variant was received. Consider upgrading the SDK to the latest available version. An unknown enum variant

Note: If you encounter this error, consider upgrading your SDK to the latest version. The Unknown variant represents cases where the server sent a value that wasn’t recognized by the client. This can happen when the server adds new functionality, but the client has not been updated. To investigate this, consider turning on debug logging to print the raw HTTP response.

Implementations§

Tries to convert the enum instance into Exact, extracting the inner String. Returns Err(&Self) if it can’t be converted.

Returns true if this is a Exact.

Tries to convert the enum instance into Prefix, extracting the inner String. Returns Err(&Self) if it can’t be converted.

Returns true if this is a Prefix.

Tries to convert the enum instance into Range, extracting the inner MatchRange. Returns Err(&Self) if it can’t be converted.

Returns true if this is a Range.

Tries to convert the enum instance into Regex, extracting the inner String. Returns Err(&Self) if it can’t be converted.

Returns true if this is a Regex.

Tries to convert the enum instance into Suffix, extracting the inner String. Returns Err(&Self) if it can’t be converted.

Returns true if this is a Suffix.

Returns true if the enum instance is the Unknown variant.

This method tests for self and other values to be equal, and is used by ==.
This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
