Struct ethcore::spec::SpecParams

pub struct SpecParams<'a> {
    pub cache_dir: &'a Path,
    pub optimization_setting: Option<OptimizeFor>,
}

Runtime parameters for the spec that are related to how the software should run the chain, rather than integral properties of the chain itself.

Fields

cache_dir: &'a Path

The path to the folder used to cache nodes. This is typically /tmp/ on Unix-like systems

optimization_setting: Option<OptimizeFor>

Whether to run slower at the expense of better memory usage, or run faster while using more memory. This may get more fine-grained in the future but for now is simply a binary option.

Implementations

impl<'a> SpecParams<'a>

pub fn from_path(path: &'a Path) -> Self

Create from a cache path, with null values for the other fields

pub fn new(path: &'a Path, optimization: OptimizeFor) -> Self

Create from a cache path and an optimization setting
