Crate partitions 

Partition-table probe (GPT/MBR) and filesystem-magic sniffer over any random-access block source.

See the crate-level README for design and scope.

Block-device abstractions come from fs_core; this crate re-exports the bits most consumers will use so callers can use partitions::BlockRead; without an extra dependency line.

Re-exports

Modules

capi

C ABI for partition probing and FS sniffing.

error

gpt

GPT (GUID Partition Table) primary header + partition entry array.

gpt_write

GPT writer.

mbr

MBR (Master Boot Record) partition table.

mutation

Partition-table mutation API.

probe

Top-level probe: try GPT first, fall back to MBR. Logical (extended-MBR) chains are not walked yet — the four primary entries are reported as-is.

sniff

Filesystem-magic sniffer. Reads a small window from the start of a partition and identifies the filesystem by its on-disk signature. This does NOT validate the filesystem — it just answers “what is this likely to be?” The driver itself does proper validation when mounting.

Structs

FileBlock

OwnedSlice

Owned slice over an Arc<dyn BlockRead>. Use when the parent’s lifetime can’t be expressed in a borrow — e.g. when the slice is handed across an FFI boundary or stored in a long-lived struct.

SliceReader

Borrowed slice of a parent BlockRead.

Traits

BlockDevice

Read-write random-access block device. Implementors that genuinely support writes override write_at / flush / is_writable. The defaults model a strict read-only device.

BlockRead

Read-only random-access block device.
