Struct QnxConfig 

pub struct QnxConfig {
    pub qnx_kernel_buffers: Option<u32>,
    pub qnx_kernel_kbuffers: Option<u32>,
    pub qnx_kernel_wide_events: Option<bool>,
    pub qnx_cache_pages: Option<u32>,
    pub qnx_cache_max_pages: Option<i32>,
    pub qnx_trace_buffer_init_bytes: Option<u32>,
}

QnxConfig is used with trace_qnx_probes build from https://github.com/qnx-ports/perfetto

Fields

qnx_kernel_buffers: Option<u32>

The number of buffers that tracelog will init for the QNX trace.

qnx_kernel_kbuffers: Option<u32>

The number of kernel buffers that tracelog will init for the QNX trace.

qnx_kernel_wide_events: Option<bool>

Flag indicating whether the QNX kernel tracing should produce wide events which contain additional data or fast events which are most concise. In fast mode we lose the priority information

qnx_cache_pages: Option<u32>

The number of pages initialized by default the parser’s page cache.

qnx_cache_max_pages: Option<i32>

The max pages the page cache should allocate (must be at least as big) as the qnx_cache_pages value. Using -1 will allow the cache to grow unbounded. The cache will prefer to re-use existing pages so growth will only happen when needed (when parser is not keeping up).

qnx_trace_buffer_init_bytes: Option<u32>

The initial size of the the buffer used to hold the trace header values this dynamic buffer will grow as needed but reallocs can be avoided by selecting an initial size large enough to hold all the initial header data.

Implementations

Returns the value of qnx_kernel_kbuffers, or the default value if qnx_kernel_kbuffers is unset.

pub fn qnx_kernel_wide_events(&self) -> bool

Returns the value of qnx_kernel_wide_events, or the default value if qnx_kernel_wide_events is unset.

pub fn qnx_cache_pages(&self) -> u32

Returns the value of qnx_cache_pages, or the default value if qnx_cache_pages is unset.

pub fn qnx_cache_max_pages(&self) -> i32

Returns the value of qnx_cache_max_pages, or the default value if qnx_cache_max_pages is unset.

pub fn qnx_trace_buffer_init_bytes(&self) -> u32

Returns the value of qnx_trace_buffer_init_bytes, or the default value if qnx_trace_buffer_init_bytes is unset.

Trait Implementations

impl Clone for QnxConfig

fn clone(&self) -> QnxConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for QnxConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for QnxConfig

fn default() -> Self

Returns the “default value” for a type.

impl Message for QnxConfig

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for QnxConfig

fn eq(&self, other: &QnxConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
