pub struct Header<'a> { /* private fields */ }
Expand description

BER/DER object header (identifier and length)

Implementations

Build a new BER/DER header from the provided values

Build a new BER/DER header from the provided tag, with default values for other fields

Set the class of this Header

Set the constructed flags of this Header

Set the tag of this Header

Set the length of this Header

Update header to add reference to raw tag

Return the class of this header.

Return true if this header has the ‘constructed’ flag.

Return the tag of this header.

Return the length of this header.

Return the raw tag encoding, if it was stored in this object

Test if object is primitive

Test if object is constructed

Return error if class is not the expected class

Return error if tag is not the expected tag

Return error if object is not primitive

Return error if object is primitive

Test if object class is Universal

Test if object class is Application

Test if object class is Context-specific

Test if object class is Private

Return error if object length is definite

Get the content following a BER header

Get the content following a DER header

Trait Implementations

Returns a copy of the value. Read more

Performs copy-assignment from source. Read more

Formats the value using the given formatter. Read more

Converts to this type from the input type.

Attempt to parse input bytes into a BER object

Attempt to parse input bytes into a DER object (enforcing constraints)

Compare two BER headers. len fields are compared only if both objects have it set (same for raw_tag)

This method tests for self and other values to be equal, and is used by ==. Read more

This method tests for !=.

Get the length of the object, when encoded Read more

Attempt to write the DER header to this writer.

Attempt to write the DER content (all except header) to this writer.

Similar to using to_der, but uses provided values without changes. This can generate an invalid encoding for a DER object. Read more

Write the DER encoded representation to a newly allocated Vec<u8>.

Similar to using to_vec, but uses provided values without changes. This can generate an invalid encoding for a DER object. Read more

Attempt to write the DER encoded representation (header and content) into this writer. Read more

Mutably borrows from an owned value. Read more

Returns the argument unchanged.

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

The resulting type after obtaining ownership.

Creates owned data from borrowed data, usually by cloning. Read more

Uses borrowed data to replace owned data, usually by cloning. Read more

Performs the conversion.
