Struct capra_core::common::gas::Gas

pub struct Gas { /* fields omitted */ }

A gas mix used in a dive.

Implementations

impl Gas

pub fn new(o2: usize, he: usize, n2: usize) -> Result<Self, GasError>

Returns a new Gas with the given parameters.

Arguments

• o2 - Percentage fraction of oxygen in the mix.
• he - Percentage fraction of helium in the mix.
• n2 - Percentage fraction of nitrogen in the mix.

Errors

This function will return a GasError if the percentage fractions do not add up to 100.

pub fn fr_n2(&self) -> f64

Returns the fraction of nitrogen in the mix.

pub fn fr_o2(&self) -> f64

Returns the fraction of oxygen in the mix.

pub fn fr_he(&self) -> f64

Returns the fraction of helium in the mix.

pub fn o2(&self) -> usize

Returns the percentage fraction of oxygen in the mix.

pub fn he(&self) -> usize

Returns the percentage fraction of helium in the mix.

pub fn n2(&self) -> usize

Returns the percentage fraction of nitrogen in the mix.

pub fn equivalent_narcotic_depth(&self, depth: usize) -> usize

Returns the Equivalent Narcotic Depth (END) of the mix at a given depth.

Arguments

• depth - The depth the mix is being breathed at.

pub fn in_ppo2_range(&self, depth: usize, min: f64, max: f64) -> bool

Helper function to check whether the mix is in an acceptable ppO2 range at a given depth.

Arguments

• depth -Depth the mix is being breathed at.
• min - Minimum tolerable ppO2.
• max - Maximum tolerable ppO2.

pub fn pp_o2(&self, depth: usize, metres_per_bar: f64) -> f64

Returns the ppO2 of the mix at a given depth.

Arguments

• depth - Depth the mix is being breathed at.
• metres_per_bar - Depth of water required to induce 1 bar of pressure.

pub fn pp_he(&self, depth: usize, metres_per_bar: f64) -> f64

Returns the ppHe of the mix at a given depth.

Arguments

• depth - Depth the mix is being breathed at.
• metres_per_bar - Depth of water required to induce 1 bar of pressure.

pub fn pp_n2(&self, depth: usize, metre_per_bar: f64) -> f64

Returns the ppN2 of the mix at a given depth.

Arguments

• depth - Depth the mix is being breathed at.
• metres_per_bar - Depth of water required to induce 1 bar of pressure.
