Struct LookupOptions 

pub struct LookupOptions {
    pub line_information: bool,
    pub inline_frames: bool,
    pub call_sites: bool,
}

Controls which optional records an allocating lookup inspects.

Every field defaults to true, which is what Gsym::lookup uses. Turning a field off skips that work entirely, so a name-only lookup costs less than a full one.

use gsym::LookupOptions;

let names_only = LookupOptions {
    line_information: false,
    inline_frames: false,
    call_sites: false,
};
assert!(LookupOptions::default().line_information);
assert!(!names_only.line_information);

Fields

line_information: bool

Resolve source files and lines.

inline_frames: bool

Resolve inline-call frames.

call_sites: bool

Resolve matching call-site patterns.

Trait Implementations

impl Clone for LookupOptions

fn clone(&self) -> LookupOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for LookupOptions

impl Debug for LookupOptions

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

Formats the value using the given formatter.

impl Default for LookupOptions

fn default() -> Self

Returns the “default value” for a type.

impl Eq for LookupOptions

impl From<FrameLookupOptions> for LookupOptions

fn from(options: FrameLookupOptions) -> Self

Converts to this type from the input type.

impl PartialEq for LookupOptions

fn eq(&self, other: &LookupOptions) -> 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.
