Expand description

Signed metadata associated with a block.

Implementations§

source§

impl BlockMeta

source

pub fn assert_valid(&self, path: &BlockPath) -> Result<()>

Validates that this metadata struct contains a valid writecap, that this writecap is permitted to write to the path of this block and that the signature in this metadata struct is valid and matches the key the writecap was issued to.

source§

impl BlockMeta

source

pub fn new<C: Creds>(creds: &C) -> Result<BlockMeta>

Creates a new BlockMeta struct which is authenticated by the given credentials.

source

pub fn body(&self) -> &BlockMetaBody

Returns a reference to the BlockMetaBody contained in this struct.

source

pub fn mut_body(&mut self) -> &mut BlockMetaBody

Returns a mutable reference to the BlockMetaBody contained in this struct.
