void Extent ()

Defined at line 257 of file ../../src/storage/blobfs/format.h

void Extent (uint64_t start_block, uint64_t length_blocks)

Create an extent starting at |start_block| blocks, spanning |length_blocks|.

|start_block| must be

<

= kBlockOffsetMax and |length_blocks| must be

<

= kBlockCountMax.
