Struct PvInfo 

pub struct PvInfo {
    pub dbr_type: Option<String>,
    pub element_count: Option<u32>,
    pub units: Option<String>,
    pub precision: Option<u32>,
    pub lower_display_limit: Option<f64>,
    pub upper_display_limit: Option<f64>,
    pub raw: BTreeMap<String, String>,
}

What getMetadata says about a PV (all optional: servers differ).

Fields

dbr_type: Option<String>

e.g. DBR_SCALAR_DOUBLE, DBR_WAVEFORM_DOUBLE, DBR_SCALAR_ENUM.

element_count: Option<u32>

units: Option<String>

precision: Option<u32>

lower_display_limit: Option<f64>

upper_display_limit: Option<f64>

raw: BTreeMap<String, String>

Every key as returned.

Implementations

impl PvInfo

pub fn is_scalar_numeric(&self) -> bool

True when optimized_N makes sense: a scalar number (or enum). Unknown types count as numeric.

pub fn binnable(&self) -> bool

True when the plot should ask for optimized_N bins: a scalar number that is not an enum. Bin means of enum state indices (1.63) name no state, so enums are fetched raw, as are waveforms and text.

Trait Implementations

impl Clone for PvInfo

fn clone(&self) -> PvInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PvInfo

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

Formats the value using the given formatter.

impl Default for PvInfo

fn default() -> PvInfo

Returns the “default value” for a type.

impl PartialEq for PvInfo

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

Equality operator ==.

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

Inequality operator !=.
