Struct EntryView 

pub struct EntryView<'a>(/* private fields */);

Zero-copy view into a 16-byte SD entry in a buffer.

Wire layout (16 bytes total):

• [0]: entry type
• [1]: index_first_options_run
• [2]: index_second_options_run
• [3]: options_count (packed nibbles)
• [4..6]: service_id (BE)
• [6..8]: instance_id (BE)
• [8]: major_version
• [9..12]: ttl (24-bit BE)
• [12..16]: minor_version (BE) for service entries, OR [12..14] counter + [14..16] event_group_id for eventgroup entries

Implementations

impl EntryView<'_>

pub fn entry_type(&self) -> Result<EntryType, Error>

Returns the entry type.

Errors

Returns Error::InvalidEntryType if the type byte is not recognized.

pub fn index_first_options_run(&self) -> u8

Returns the index of the first options run.

pub fn index_second_options_run(&self) -> u8

Returns the index of the second options run.

pub fn options_count(&self) -> OptionsCount

Returns the packed options count.

pub fn service_id(&self) -> u16

Returns the service ID.

pub fn instance_id(&self) -> u16

Returns the instance ID.

pub fn major_version(&self) -> u8

Returns the major version.

pub fn ttl(&self) -> u32

Returns the TTL (24-bit value).

pub fn minor_version(&self) -> u32

Minor version (only valid for service entries).

pub fn counter(&self) -> u16

Counter field (only valid for eventgroup entries). Masked to lower 4 bits.

pub fn event_group_id(&self) -> u16

Event group ID (only valid for eventgroup entries).

pub fn to_owned(&self) -> Result<Entry, Error>

Converts this view into an owned Entry.

Errors

Returns Error::InvalidEntryType if the entry type byte is not recognized.
