You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: _project_status.rs
    path of file: ./repos/aws-sdk-rust/sdk/codestar/src/types
    
    the code of the file until where you have to start completion: // Code generated by software.amazon.smithy.rust.codegen.smithy-rs. DO NOT EDIT.

/// <p>An indication of whether a project creation or deletion is failed or successful.</p>
#[non_exhaustive]
#[derive(::std::clone::Clone, ::std::cmp::PartialEq, ::std::fmt::Debug)]
pub struct ProjectStatus {
    /// <p>The phase of completion for a project creation or deletion.</p>
    pub state: ::std::string::String,
    /// <p>In the case of a project creation or deletion
    
    pub fn build(self) -> ::std::result::Result<crate::types::ProjectStatus, ::aws_smithy_types::error::operation::BuildError> {
        ::std::result::Result::Ok(crate::types::ProjectStatus {
            state: self.state.ok_or_else(|| {
                ::aws_smithy_types::error::operation::BuildError::missing_field(
                    "state",
                    "state was not specified but it is required when building ProjectStatus",
                )
            })?,
            reason: self.reason,
        })
    }
